The pause after a PAC is usually incomplete ; i.e., the PAC usually enters the sinus node and resets its timing, causing the next sinus P to appear earlier than expected.

Supraventricular tachycardia (SVT) is an abnormally rapid cardiac rhythm with narrow‐complex (supraventricular) QRS morphology on the electrocardiogram. Rarely, wide QRS morphology occurs as a result of abnormal delayed conduction through the right or left bundle branches (i.e., SVT with aberrancy).
WebSupraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. This is in contrast to the other group of fast heart rhythms – … Web2 apr 2024 · Narrow QRS tachycardia is defined as a tachycardia (heart rate >100) with narrow QRS (duration <120 ms). Narrow QRS indicates simultaneous activation of both ventricles. Atrial tachycardias generally have a narrow QRS because their ventricular activation occurs via the AV node and the ventricular conduction system (His-Purkinje …
