Atrial extrasystoles

Authoring team

These have abnormal P waves; a junctional extrasystole either has no P wave at all, or it may occur immediately before or immediately following the QRS complex.

A patient with atrial or nodal extrasystoles will have an ECG with QRS complexes that are the same of those of sinus rhythm.

ECG findings are that a nodal extrasystole has no P wave; an abnormal shaped P wave is present in an atrial extrasystole.
