We recorded a regular sinus rhythm, an AH interval was 150 ms, and HV interval
was -24 ms.
The electrophysiological study showed a baseline prolonged AH (147 ms) and HV interval
(75 ms); the programmed ventricular stimulation, using up to triple extrastimuli, revealed a sustained right bundle ventricular tachycardia (VT) with right inferior axis and cycle length of 290 ms, treated by external DC shock.
At the end of the 30-minute postablation waiting period, there was no preexcitation and HV interval
measured 51 msec.
