Mode Descriptions
VVI
(Ventricular Pacing, Sensing, and Inhibition)
In VVI mode, the device paces the ventricle(s) at the programmed rate if it does not detect a sensed
event. If the device detects a sensed event during the alert period, it withholds the pulse and it resets
the timing period to the start of the Ventricular Refractory Period.

VOO
(Ventricular Asynchronous Pacing)
In VOO mode, the device paces the ventricle(s) at the programmed rate regardless of the intrinsic
rhythm.
CAUTION
VOO mode is primarily intended for temporary use. Long-term use
may result in competitive pacing, which may induce potentially
dangerous tachyarrhythmias.
