Distortion of intracardiac electrograms following defibrillator shocks for atrial tachyarrhythmias

Abstract

In three patients with a defibrillator system consisting of a Ventak P2 pulse generator and an Endotak C transvenous lead, we observed distortion of intracardiac electrograms following defibrillator shocks for atrial arrhythmias. There was a transient marked widening of the intracardiac ventricular complexes resembling ventricular tachycardia. This phenomenon should be recognized when evaluating arrhythmic episodes.
