Multifocal PVCs have different sites of origin, which means their coupling intervals measured from the previous QRS complexes are usually different.
Multiformed PVCs usually have the same coupling intervals because they originate in the same ectopic site but their conduction through the ventricles differ. Multiformed PVCs are common in digitalis intoxication. PVCs may occur as isolated single events or as couplets, triplets, and salvos PVCs in a rowalso called brief ventricular tachycardias.
PVCs may occur early in the cycle R-on-T phenomenonafter the T wave as seen aboveor late in the cycle - often fusing with the next QRS fusion beat. R-on-T PVCs may be especially dangerous in an acute ischemic situation, because the ventricles may be more vulnerable to ventricular tachycardia or fibrillation.
Examples are seen below. The events following a PVC are of interest. Usually a PVC is followed by a complete compensatory pause because the sinus node timing is not interrupted; 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 the sinus rate.
In contrast, PACs are usually followed by an incomplete pause because the PAC usually enters the sinus node and resets its timing; this enables the following sinus P wave to appear earlier than expected.
These concepts are illustrated below.
Not all PVCs are followed by a pause. If a PVC occurs early enough especially if the heart rate is slowit may appear sandwiched in between two normal beats. This is called an interpolated PVC. The sinus impulse following the PVC may be conducted with a longer PR interval because of retrograde concealed conduction by the PVC into the AV junction slowing subsequent conduction of the sinus impulse.
The most unusual post-PVC event is when retrograde activation of the AV junction re-enters the ventricles as a ventricular echo.
This is illustrated below. The "ladder" diagram below the ECG helps us understand the mechanism. PVCs usually stick out like "sore thumbs", because they are bizarre in appearance compared to the normal complexes.
However, not all premature sore thumbs are PVCs. The challenge, therefore, is to recognize sore thumbs for what they are, and that's the next topic for discussion!
The phenomenon comes about because of unequal refractoriness of the bundle branches and critical prematurity of a supraventricular impulse see diagram of Three Fates of PACs. With such critical prematurity, the supraventricular impulse encounters one bundle branch or fascicle which is responsive, and the other which is refractory, and is consequently conducted with a bundle branch block or fascicular block pattern.
Preceding ectopic P wave i.
Analyze the compensatory pause: A complete pause favors ventricular ectopy i. An incomplete pause favors aberration i. Be aware of exceptions to this simple rule because PVCs can activate the atria retrogradely and reset the sinus node incomplete pauseand PACs can fail to reset the sinus node complete pause.
Long-Short Rule Ashman Phenomenon: This is because the refractory period of the ventricular conduction system is proportional to cycle length or heart rate; the longer the cycle length or slower the heart rate, the longer the recovery time of the conduction system.
In diseased hearts, however, LBBB aberrancy is also seen. Richard Ashman and colleagues first described this in in patients with atrial fibrillation.
That's all it takes to get your name attached to a phenomenon; you must publish! Analyze the QRS morphology of the funny-looking beat. This is one of the most rewarding of the clinical clues, especially if lead V1 or the MCL1 monitored lead in intensive care units is used.I See the Tree – Vowel Team /ee/ Resource ID#: Primary Type: Lesson Plan.
