Abstract:
1. A method comprising: delivering stimulation energy via a right ventricular site; sensing an evoked response caused by the delivered stimulation energy at the right ventricular site; calculating a paced propagation delay for the right ventricular site (PPD delivering stimulation energy via a left ventricular site; sensing an evoked response caused by the delivered stimulation energy at the left ventricular site; calculating a paced propagation delay for the left ventricular site (PPD determining an interventricular delay time (VV) for delivery of a bi-ventricular pacing therapy based in part on the paced propagation delay for the right ventricular site (PPD calculating a time difference between the paced propagation delay for the right ventricular site and the paced propagation delay for the left ventricular site (ΔPPD) and using this time difference as an estimate for a time difference (Δ
