WebDec 2, 2024 · A premature atrial complex (PAC) is a premature beat arising from ectopic pacemaking tissue within the atria. There is an abnormal P wave, usually followed by a normal QRS complex. AKA: Atrial ectopics, atrial extrasystoles, atrial premature beats, atrial premature depolarisations. ECG features of PACs WebThe T wave on the ECG is the positive deflection after the QRS complex. It represents the repolarization of the ventricular myocardium. To understand the T wave, let’s first briefly go over depolarization and repolarization.
