HV interval

HV in·ter·val

the time from the initial deflection of the His bundle (H) potential and the onset of ventricular activity (normally 35-45 msec).

HV interval

[in′tərvəl]
the conduction time of an impulse traveling through the His-Purkinje system. It is measured from the onset of the atrioventricular bundle potential to the onset of ventricular activation as recorded on an electrogram.

HV in·ter·val

(in'tĕr-văl)
The time from the initial deflection of the His bundle (H) potential and the onset of ventricular activity (normally 35-45 msec).

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.
