Figure 1 A: Interrogation strip from pacemaker showing an atrial sensed, ventricular paced rhythm with abrupt onset of polymorphic ventricular tachycardia (PVT) (asterisk marks first ventricular sensed event). The atrial rate is irregular, representing premature atrial complexes. The atrial sensed events following the asterisk likely represent far-field sensing of ventricular tachycardia by the atrial lead. B: Device-stored electrogram showing PVT with spontaneous termination after approximately 7 seconds.
