safety pacing-ventricular

safety pacing–ventricular

Cardiac pacing In some A-V sequential–DVI and A-V universal–DDD pacemakers, following atrial pacing, the pacemaker is designed to trigger a ventricular pacing output if ventricular sensing occurs during the first portion–e.g., 110 ms of the programmed A-V interval. See Pacemaker.
