Abstract
A pacing protocol is provided that reduces or minimizes ventricular pacing in favor of intrinsic conduction. When operating in a mode that provides ventricular pacing, a series of conduction checks are performed to determine if intrinsic conduction has returned. These conduction checks occur according to a predetermined pattern that generally includes longer intervals between subsequent attempts. The AV interval provided for dual chamber based pacing is modulated and generally moves from a larger value to a nominal value as the interval between unsuccessful conduction checks increases.
