Patient 1. A: Rhythm strip on admission showing supraventricular tachycardia of 250 beats per minute, triggering polymorphic ventricular tachycardia (VT). This run of polymorphic VT lasted 13.2 seconds and converted to sinus rhythm spontaneously. The coupling interval of the initiating beat was 310 ms. Following conversion to sinus rhythm multiple premature ventricular contractions (PVCs) were observed with 2 morphologies. The first PVC had a right inferior axis whereas the subsequent PVCs had left superior axis (similar to the PVC initiating polymorphic VT). B: Normal 12-lead electrocardiogram during sinus rhythm.
