Abstract
Primarily, the invention relates to a safe delivery of atrial cardioversion pulses in complex cardiac therapy environments wherein cardiac events suggest, for example, rapid ventricular rates that would prevent a safe atrial cardioversion. The invention generally utilizes an algorithmic system in which a resultant R-R interval encountered subsequent to the delivery of a ventricular pacing pulse is decrementally scanned until an R-R interval is found that will yield a reliable sustained R-R interval. The sustenance of the R-R interval prolongation enables ventricular deceleration. Strategically selected timing windows are used to trigger a device response that is proper and tailored to the ventricular event detected during and within the timing windows. Further, the invention enables an atrial cardioversion synchronization method that allows for the safe delivery of atrial cardioversion pulses in the presence of very rapid ventricular rates.
