How VSP Operates
When VSP is programmed ON, a ventricular sense within 110 ms after an
atrial pacing pulse results in a ventricular pacing pulse at 110 ms (see
illustration below) or at the programmed PAV interval, whichever expires
first. If the sensed event was, in fact, a ventricular depolarization, the
ventricular pacing pulse at 110 ms falls harmlessly into the absolute
refractory period of the ventricle.
