Abstract:
1. A method for programming an atrio-ventricular (A-V) delay interval for a bi-ventricular implantable pulse generator, comprising: determining an inter-atrial conduction time (IACT) between an evoked depolarization of a right atrium (RA) and a conducted depolarization of a left atrium (LA); calculating an atrio-ventricular (AV) delay interval based upon the IACT, wherein the calculating step comprises adding about 100 milliseconds to the IACT value to produce a resulting value and reducing the resulting value by about 31 percent; and subsequently delivering for at least one cardiac cycle a bi-ventricular pacing therapy to a right ventricle (RV) and to a left ventricle (LV) upon expiration of the calculated AV delay interval.
