A recent ski trip at high altitude resulted in an increase in BP, and the appearance of PACS for the first time. If your cardiologist cant tell if it a PVC or PAC, then you should be refered to an Electrophysiolost, - a cardiologist who specializes in heart rhythms. Atrial fib is where the atrium fires irregularly and needs to be treated. For patients who experience either PVCs or  PACs the AliveCor device is frequently inaccurate. Indeed, all of them but one showed NSR. Escape rate is usually 30-50 bpm (i.e., slower than a junctional escape rhythm). How can I differentiate a 2nd Degree AVB from a non-conducted PAC?

Sometimes patients feel these premature beats as a skipping or irregularity of the heart beat. Dr. Grauer is the sole proprietor of KG-EKG Press, and publisher of an ECG pocket brain book. The red line at the beginning of Figure 2 measures two normal P-P intervals. If you feel like your heart occasionally skips a beat, you could actually be having an extra heartbeat. Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in the ventricles, or lower pumping chambers, and disrupt your regular heart rhythm, sometimes causing you to feel a skipped beat or palpitations. Rhythm analysis indicates normal sinus rhythm (NSR) at 68 bpm. However, if you have frequent PVCs, your doctor might recommend treatment.In some cases, if you have heart disease that could lead to more-serious rhythm problems, you might need the following: 1. Advanced heart disease (e.g., coronary heart disease) statistically favors ventricular tachycardia. PVCs may occur early in the cycle (R-on-T phenomenon), after the T wave (as seen above), or late in the cycle - often fusing with the next QRS PVCs with different focal points will look different and are multiform or multifocal PVCs . for it to have caused the next QRS.

I had a follow up 24 holter monitor last week stemming from a bad episode of PVCs (trigeminy) caught on my ECG at the ER. I see a cardiologist about 2 times a yr. and have an echo usually yearly, have one scheduled for March before I see him. It is a bit unusual in that one PAC is followed by a compensatory pause and the other by a non-compensatory pause. PVC's are irregular beats that start in one of the 2 bottom chambers. Accelerated ventricular rhythms. To differentiate between a complete pause and an incomplete pause, the underlying rhythm must be regular. I live in Utah but would love to be able to send you recordings to review for me even if there is a fee. They can be patterened, but that is unusual.

The authors report that, from a single 12-lead electrocardiogram, one premature atrial contraction (PAC) predicts incident atrial fibrillation (AF) and death, and one premature ventricular contraction (PVC) predicts incident heart failure and death. When you see monitor alarming for multiple PAC and PVC ... What should I do? It has made living with pvc, pacs, short runs of afib much easier. Although this is an ECG tutorial, let's not forget some simple bedside clues to ventricular tachycardia: A "passive" escape rhythm that occurs by default whenever higher-lever pacemakers in AV junction or sinus node fail to control ventricular activation. Both can be normal but the PVC can become more problematic with the type and frequency. (Remember, the PR interval following an interpolated PVC is usually longer than normal, not shorter!). Agree with Johan definitely. Contrary to popular belief, PACs followed by compensatory pauses are not rare. Such premature atrial contractions (PACs) have generally been considered benign in the past but a recent study showed that frequent (>30 s per hour) PACs or runs of >20 PACs in a row were associated with a doubling of stroke risk. About 4 years ago they went away. I happen to know something about electrocardiography and they are classic examples. Replies. Differential diagnosis of wide QRS tachycardias. Strongly consider having the tracing reviewed by a cardiologist before concluding that you had afib. Most times they are asymptomatic and, in general, they are considered benign.

PACs do not typically cause damage to the heart and can occur in healthy individuals with no known heart disease. with an abnormal ECG (73.2 ±15.6 vs 75.2 16.8, P < 0.001). PAC's are much less serious then PVC's. their coupling intervals (measured from the previous QRS complexes) are usually different. intervals (because they originate in the same ectopic site but their conduction through the ventricles differ. Usually a PVC is followed by a complete compensatory pause because the sinus node timing is not interrupted; 2. I am seeing a cardiologist as I just don’t fee well as it is happening so often. 0 Likes. A premature ventricular contraction (PVC) is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node.PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest. Isolated PACs and PVCs are never dangerous – they're just a sign that your heart is responding to something. the ectopic activation sequence. Figure 12: Ventricular escape.

When you see monitor alarming for multiple PAC and PVC ... What should I do? It has made living with pvc, pacs, short runs of afib much easier. Although this is an ECG tutorial, let's not forget some simple bedside clues to ventricular tachycardia: A "passive" escape rhythm that occurs by default whenever higher-lever pacemakers in AV junction or sinus node fail to control ventricular activation. Both can be normal but the PVC can become more problematic with the type and frequency. (Remember, the PR interval following an interpolated PVC is usually longer than normal, not shorter!). Agree with Johan definitely. Contrary to popular belief, PACs followed by compensatory pauses are not rare. Such premature atrial contractions (PACs) have generally been considered benign in the past but a recent study showed that frequent (>30 s per hour) PACs or runs of >20 PACs in a row were associated with a doubling of stroke risk.

A recent ski trip at high altitude resulted in an increase in BP, and the appearance of PACS for the first time. If your cardiologist cant tell if it a PVC or PAC, then you should be refered to an Electrophysiolost, - a cardiologist who specializes in heart rhythms. Atrial fib is where the atrium fires irregularly and needs to be treated. For patients who experience either PVCs or  PACs the AliveCor device is frequently inaccurate. Indeed, all of them but one showed NSR. Escape rate is usually 30-50 bpm (i.e., slower than a junctional escape rhythm). How can I differentiate a 2nd Degree AVB from a non-conducted PAC?

Not all PVCs are followed by a pause. example) are most often ventricular ectopic in origin. Hi everyone - What is the difference when you feel a PAC vs a PVC?? Sometimes patients feel these premature beats as a skipping or irregularity of the heart beat. Dr. Grauer is the sole proprietor of KG-EKG Press, and publisher of an ECG pocket brain book. The red line at the beginning of Figure 2 measures two normal P-P intervals. If you feel like your heart occasionally skips a beat, you could actually be having an extra heartbeat. Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in the ventricles, or lower pumping chambers, and disrupt your regular heart rhythm, sometimes causing you to feel a skipped beat or palpitations. Rhythm analysis indicates normal sinus rhythm (NSR) at 68 bpm. However, if you have frequent PVCs, your doctor might recommend treatment.In some cases, if you have heart disease that could lead to more-serious rhythm problems, you might need the following: 1. Advanced heart disease (e.g., coronary heart disease) statistically favors ventricular tachycardia. PVCs may occur early in the cycle (R-on-T phenomenon), after the T wave (as seen above), or late in the cycle - often fusing with the next QRS PVCs with different focal points will look different and are multiform or multifocal PVCs . for it to have caused the next QRS. Sooner or later they risk being obsoleted by low cost ecg+ patches. Where were the PVCs?? Premature atrial complexes (PACs), Premature junctional complexes (PJCs), and Premature ventricular contractions (PVCs) are present. Since then, I’ve come across a handful of similar misdiagnoses. rate of the parasystolic focus, PVCs have uniform morphology unless fusion beats occur, Fusion beats are common when ectopic site fires while ventricles are already being activated from primary pacemaker, Parasystolic rhythms may also be seen in the atria and AV junction. Premature contraction are classified by their origin: atrial (premature atrial contraction, PAC), junctional (premature junctional contraction, PJC), ventricular (premature ventricular contraction, PVC) ECG Features. Reply Delete. ECTOPIC HEARTBEATS CAN BE SCARY I have had a few ectopic heartbeats in my time and it can be very scary! I obtained the “Normal”  tracing below from a patient in my office with a biventricular pacemaker and frequent PVCs who had no symptoms. I just received the results and all that was detected was 6 PACS!! Those that start in the lower chambers are premature ventricular contractions, or PVCs. Be the best at electrocardiography!

pac vs pvc ecg

The recordings can also be emailed to me. concealed conduction by the PVC into the AV junction slowing subsequent conduction of the sinus impulse. ECG Review. These concepts are illustrated below. Retrograde atrial activation: Occasionally the ventricular impulse may be conducted backwards through the bundle of His in to the atria and depolarize both the atria and the sinoatrial node. The premature ectopic beat may arise from several different origins and are classified as atrial (PAC), junctional (PJC), or ventricular (PVC). enables the following sinus P wave to appear earlier than expected. Anthony C. Pearson, MD, FACC is a cardiologist focused on debunking cardiovascular myths and identifying best methods for utilizing lifestyle medications and procedures to promote cardiovascular health.If you are a potential patient and found this page through a Google search, please check out Dr. Pearson’s biographical information, disclaimers regarding his writings, and notice to patients here. Atrial fib is where the atrium fires irregularly and needs to be treated. The first 3 beats are NSR. Eliminating common PVC triggers — such as caffeine or tobacco — can decrease the frequency and severity of your symptoms. I have bigeminy and skipped every beat which I can’t seem to find a name for, How are you feeling now ? Consequently, if you have afib and premature beats you cannot be entirely confident that a reading of afib is truly afib. Another time because my heart beat was fast its result ‘unclassified ‘ confusing as purpose of recording is to confirm and show these changes. Often the retrograde P wave can be seen Both new Apple Watch 4 and the Kardia band on the old AW3 indicated irregularities. You will agree … Continue reading ECTOPIC HEARTBEATS, PVC AND PAC BEATS. Premature beats sometimes are interpreted by AliveCor as normal. Thank you. Started with PVC’s when I was diagnosed with Graves Disease. Spent a couple of hrs. The other 3 recordings identified by AliveCor as afib are actually normal sinus rhythm with premature beats. → With AV dissociation these Presence of fusion QRS complexes (Dressler beats) which occur when supraventricular beats (usually sinus) get into the ventricles during of the basic Here’s the deal. I’ve had arrhythmia issues for 19 years. the sinus rate. Paced beats (blue arrows) PVCs (red arrows). This resets the clock of the sinoatrial node. I am a 63 year old obese male. Single beat PVCs do not usually pose a danger. PVCs Read As Normal . in digitalis intoxication. How certain are you of your answer? PVCs may be unifocal (see above), multifocal (see below) or multiformed. PAC will have a different p wave morphology and since they are premature they will come sooner than you expect the next beat. What is clear is that premature beats  significantly confuse the AliveCor algorithm. PAC: Premature Atrial Contraction Pic 2 shows 2 occurrences of PAC (beat 3 and 7) where a P wave comes before it should which makes the pre-ceding T wave look abnormally large. Both PVCs and PACs can create a false positive diagnosis of atrial fibrillation when it is not present. I have an EKG which I initially interpreted as Mobitz I, but which apparently is blocked PAC according to an automated analysis. one sinus P wave isn't able to reach the ventricles because they are still refractory from the PVC; the following sinus impulse occurs on time based on i have alot of symptomatic pvc beats too in bigeminy (mostly at rest). Her PVCs are sufficiently early and with low voltage so the AliveCor algorithm cannot differentiate them from T Waves and only counts the normal sinus beats toward heart rate. Kardia is going to classify sinus rhythm with premature beats (PVCS or PACs) as “normal” most of the time. I haven’t established any method for charging fees but I am sorry, but this site is only supported in an strict HTML compliant browser. Amal Mattu’s ECG Case of the Week – March 16, 2015. If a PVC occurs early enough (especially if the heart rate is slow), it may appear sandwiched in between two It’s quite uncertain why they can’t solve the PVC issue. An ectopic pacemaker fires early before the next scheduled beat. Best regards, PVC and PAC in ECG rhythm. giant a-waves occur irregularly. This means that the heart rate is between 50 and 100 beats per minute, there are no or very few abnormal beats, and the shape, timing and duration of each beat is considered normal. P.S. PVC therapies: From a clinical perspective it is useful to divide patients with frequent PVCs into those with and those without structural heart disease: PVCs in patients with structural heart disease such as LVH, cardiomyopathy, and congestive heart failure, prior myocardial infarction, etc. Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). A premature ventricular contraction (PVC) is a premature beat coming from somewhere in the ventricles. The P wave following the PVC is the sinus P wave, but the PR interval is too short Big difference,: PAC's originate in the atrium as the PVC's originate from the ventricle. Firefox or Google Chrome. Is this atrial trigeminy? test. on the monitor and sent home with report of PAC’s. In some cases he is having isolated PVCs: They're also called: 1. A premature ventricular contraction (PVC) is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node.PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest. Lifestyle changes. Cholesterol and … PVC With Venticular Echo; Nonconducted PACs and Junctional Escapes; Nonconducted And Conducted PAC's; PAC and PVC: Complete vs. A PAC results in an electrical impulse coming earlier than expected, and in most cases causes an extra contraction of the heart. A PVC is an extra electrical impulse arising from one of the cardiac ventricles. If the wide QRS morphology is predominately, Sustained (lasting >30 sec) vs. nonsustained, Monomorphic (uniform morphology) vs. polymorphic vs. Torsade-de-pointes, Presence of AV dissociation (independent atrial activity) vs. retrograde atrial capture. In this tracing he has atrial bigeminy and a PVC. Not all PVCs are followed by a pause. Ventricular tachycardia. A recent ski trip at high altitude resulted in an increase in BP, and the appearance of PACS for the first time. If your cardiologist cant tell if it a PVC or PAC, then you should be refered to an Electrophysiolost, - a cardiologist who specializes in heart rhythms. Atrial fib is where the atrium fires irregularly and needs to be treated. For patients who experience either PVCs or  PACs the AliveCor device is frequently inaccurate. Indeed, all of them but one showed NSR. Escape rate is usually 30-50 bpm (i.e., slower than a junctional escape rhythm). How can I differentiate a 2nd Degree AVB from a non-conducted PAC? In the last few years, however, a number of studies have started to suggest that persons with PACs may actually… Facebook Twitter LinkedIn Print Email × You must be a member to content. You would have to judge as to whether the PAC came early enough to be during the refractory period. There seems to be some sort of pattern to it. Of these 10% were couplets or salvos, 21% had multiform morpholo-gies, and 15% had ventricular bigeminal or trigem-inal patterns. Variable intensity of the S1 heart sound at the apex (mitral closure); again this is seen when there is AV dissociation resulting in varying This is called an interpolated PVC. Last one and 1/2 years had increased to average of one PAC every 7-8 seconds on average. Cases by Month Cases by Month. Patient has a history of acute cholecystitis. Specializes in ICU/CVICU. PAC's are much less serious then PVC's. Because this extra impulse appears early (that is, before the next normal heartbeat has a chance to occur), it is called "premature." I have experienced every one of the items you discussed about on multiple occasions. I don’t know who was reading these but I have a recent trace with 5 consecutive PVCs that was deemed no problem. In this patient’s case, every other beat was a PVC (red circles). Origin of Ectopic Beats. If you want to email your unclassified tracings to DRP@theskepticalcardiologist.com I can review them as time allows, I have a kardia app but it says each time it’s a normal reading even though occasionally I’m feeling a couple of missed beats or pause. The phenomenon comes Ventricular escape No P, wide, bizarre QRS. After each heartbeat, there should be a slight pause and then the heartbeat resumes. Almost always with a medication to stop blood clots and for regulation. Amal Mattu’s ECG Case of the Week – June 10, 2019. I can't work out how to upload it here, but it's anonymized, and I'd really appreciate you … In the ECG below note the arrow pointing at a premature P wave in the ST-T segment. Figure-1: Lead II rhythm strip obtained from a patient with palpitations. normal beats. SEE FULL CASE. 5-3. PVCs usually stick out like "sore thumbs", because they are bizarre in appearance compared to the normal complexes. Not all PVCs are followed by a pause. example) are most often ventricular ectopic in origin. Hi everyone - What is the difference when you feel a PAC vs a PVC?? Sometimes patients feel these premature beats as a skipping or irregularity of the heart beat. Dr. Grauer is the sole proprietor of KG-EKG Press, and publisher of an ECG pocket brain book. The red line at the beginning of Figure 2 measures two normal P-P intervals. If you feel like your heart occasionally skips a beat, you could actually be having an extra heartbeat. Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in the ventricles, or lower pumping chambers, and disrupt your regular heart rhythm, sometimes causing you to feel a skipped beat or palpitations. Rhythm analysis indicates normal sinus rhythm (NSR) at 68 bpm. However, if you have frequent PVCs, your doctor might recommend treatment.In some cases, if you have heart disease that could lead to more-serious rhythm problems, you might need the following: 1. Advanced heart disease (e.g., coronary heart disease) statistically favors ventricular tachycardia. PVCs may occur early in the cycle (R-on-T phenomenon), after the T wave (as seen above), or late in the cycle - often fusing with the next QRS PVCs with different focal points will look different and are multiform or multifocal PVCs . for it to have caused the next QRS. Sooner or later they risk being obsoleted by low cost ecg+ patches. Where were the PVCs?? Premature atrial complexes (PACs), Premature junctional complexes (PJCs), and Premature ventricular contractions (PVCs) are present. Since then, I’ve come across a handful of similar misdiagnoses. rate of the parasystolic focus, PVCs have uniform morphology unless fusion beats occur, Fusion beats are common when ectopic site fires while ventricles are already being activated from primary pacemaker, Parasystolic rhythms may also be seen in the atria and AV junction. Premature contraction are classified by their origin: atrial (premature atrial contraction, PAC), junctional (premature junctional contraction, PJC), ventricular (premature ventricular contraction, PVC) ECG Features. Reply Delete. ECTOPIC HEARTBEATS CAN BE SCARY I have had a few ectopic heartbeats in my time and it can be very scary! I obtained the “Normal”  tracing below from a patient in my office with a biventricular pacemaker and frequent PVCs who had no symptoms. I just received the results and all that was detected was 6 PACS!! Those that start in the lower chambers are premature ventricular contractions, or PVCs. Be the best at electrocardiography!

Multiformed PVCs are common I have these for 30 years I can feel everyone, that’s why it is so hard to live with for me. AliveCor’s Official Position on Premature Beats. Electrocardiogram, or EKG. position of the mitral valve leaflets depending on the timing of atrial and ventricular systole. Some of you know exactly what I mean. On the other hand if you are experiencing palpitations and make a recording with Alivecor that comes back as normal do not assume that your heart rhythm was totally normal. These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest.Premature ventricular contractions are common — they occur in many people. I have had the problem you are describing of AliveCor Kardia interpreting PVCs as possible afib. If we correct the underlying trigger, the skipped beats will go away. Both can be normal but the PVC can become more problematic with the type and frequency. By Ken Grauer, MD, Professor, Department of Community Health and Family Medicine, University of Florida. One of my patients began experiences period palpitations 5 years after an ablation for atrial fibrillation. Non-fixed coupled PVCs where the inter-ectopic intervals (i.e., timing between PVCs) are some multiple (i.e., 1x, 2x, 3x, . I had a follow up 24 holter monitor last week stemming from a bad episode of PVCs (trigeminy) caught on my ECG at the ER. I see a cardiologist about 2 times a yr. and have an echo usually yearly, have one scheduled for March before I see him. It is a bit unusual in that one PAC is followed by a compensatory pause and the other by a non-compensatory pause. PVC's are irregular beats that start in one of the 2 bottom chambers. Accelerated ventricular rhythms. To differentiate between a complete pause and an incomplete pause, the underlying rhythm must be regular. I live in Utah but would love to be able to send you recordings to review for me even if there is a fee. They can be patterened, but that is unusual. Some nurses will say it's sinus arrythmia and some say they're just PAC's. Log in Now. Note differing appearance of the P waves for Sinus Rhythm vs. Atrial Escape Rhythm. The stroke risk is what I am concerned about. The ECG criteria for premature atrial contractions (PACs) including atrial bigeminy and blocked (non-conducted) PACs are discussed with links to 12-lead ECG examples. Under these circumstances atrial contractions If your heart has been proven to be healthy otherwise, any further treatment such as an ablation requires consultation with an EP specialized cardiologist. Swtooth . Dr. Grauer reports no other financial relationship to … The inaccuracies worry me but if the ekg strip is accurate, but the “findings” are not, I don’t think I should be too worried. Posted on August 28, 2019 April 7, 2020 by SonoHealth Content. This content is for members only. Specialties CCU. Premature ventricular complexes 2. One condition that causes this extra beat is premature atrial contractions. Curious in this product. R-on-T PVCs may be especially dangerous in an acute ischemic situation, because the ventricles may be more vulnerable to ventricular Before watching this week’s video… To view the remainder of this post you must be logged in or have an ECGWeekly account. Is widened beat #12 a PVC or aberrantly conducted PAC? The compensatory pause is called a complete pause because it equals two R-R intervals. Michaelccc. They have been in bigeminy, trigeminy and quadrigemiy in different readings. Finally a PVC may retrogradely capture the atrium, reset the sinus node, and be followed by an incomplete pause. Is that possible? Hi everyone - What is the difference when you feel a PAC vs a PVC?? Rapid downstroke of the S wave with or without a preceding "thin" r wave suggests LBBB aberrancy almost always! If you cannot view this post and are logged in, then the post is outside of your subscription coverage. These tracings from a woman with paroxysmal atrial fibrillation  are typical: all the Normal readings are truly normal and all the atrial fibrillation readings are truly atrial fibrillation with heart rates  above 100. they may be supraventricular tachycardias with bundle branch block or WPW preexcitation)! The authors report that, from a single 12-lead electrocardiogram, one premature atrial contraction (PAC) predicts incident atrial fibrillation (AF) and death, and one premature ventricular contraction (PVC) predicts incident heart failure and death. When you see monitor alarming for multiple PAC and PVC ... What should I do? It has made living with pvc, pacs, short runs of afib much easier. Although this is an ECG tutorial, let's not forget some simple bedside clues to ventricular tachycardia: A "passive" escape rhythm that occurs by default whenever higher-lever pacemakers in AV junction or sinus node fail to control ventricular activation. Both can be normal but the PVC can become more problematic with the type and frequency. (Remember, the PR interval following an interpolated PVC is usually longer than normal, not shorter!). Agree with Johan definitely. Contrary to popular belief, PACs followed by compensatory pauses are not rare. Such premature atrial contractions (PACs) have generally been considered benign in the past but a recent study showed that frequent (>30 s per hour) PACs or runs of >20 PACs in a row were associated with a doubling of stroke risk. About 4 years ago they went away. I happen to know something about electrocardiography and they are classic examples. Replies. Differential diagnosis of wide QRS tachycardias. Strongly consider having the tracing reviewed by a cardiologist before concluding that you had afib. Most times they are asymptomatic and, in general, they are considered benign. Almost always with … Thank you for your really helpful posts! ECG clues to the differential diagnosis of wide QRS premature beats: If the QRS in V1 is mostly positive the following possibilities exist: If the QRS in V1 is mostly negative the following possibilities exist: Another QRS morphology clue from Lead V6: The timing of the premature wide QRS complex is also important because aberrantly conducted QRS complexes only occur early in the cardiac I have many PVCs PA C’s and short bursts of afib I understand everything you are saying about the alivecor even though I do love mine as well I would be very interested in being able to send you an occasional reading to look at for me even for a fee what would I have to do to be one of your patientsand get this service. What is premature ventricular contractions (PAC, PJC, PVC)?Studying for a nursing school exam? For most people, PVCs with an otherwise normal heart won't need treatment. Join PracticeUpdate Now × You've saved your first item. For this patient,, the AliveCor frequently diagnoses “possible atrial fibrillation” but  all of his episodes turn out not to be afib. PACs do not typically cause damage to the heart and can occur in healthy individuals with no known heart disease. with an abnormal ECG (73.2 ±15.6 vs 75.2 16.8, P < 0.001). PAC's are much less serious then PVC's. their coupling intervals (measured from the previous QRS complexes) are usually different. intervals (because they originate in the same ectopic site but their conduction through the ventricles differ. Usually a PVC is followed by a complete compensatory pause because the sinus node timing is not interrupted; 2. I am seeing a cardiologist as I just don’t fee well as it is happening so often. 0 Likes. A premature ventricular contraction (PVC) is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node.PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest. Isolated PACs and PVCs are never dangerous – they're just a sign that your heart is responding to something. the ectopic activation sequence. Figure 12: Ventricular escape.
