Abstract
A method and system for ventricular fusion prevention is provided. It is determined whether an atrial sense occurred within a prior wait time and a scheduled ventricular pace is administered if no atrial sense occurred. If an atrial sense occurred and a ventricular sense follows within an additional wait time, the scheduled ventricular pace is canceled to avoid a fusion beat. If an atrial sense occurred and no ventricular sense follows within an additional wait time, the scheduled ventricular pace is administered. In another embodiment, the max AV interval is increased if too many scheduled ventricular paces are canceled to avoid fusion beats.
