Title: Selective resynchronization therapy optimization based on user preference

Abstract: A method and system for calculating an atrio-ventricular delay interval based upon an inter-atrial delay exhibited by a patient's heart. The aforementioned atrio-ventricular delay interval may optimize the stroke volume exhibited by a patient's heart. The aforementioned atrio-ventricular delay interval may be blended with another atrio-ventricular delay interval that may optimize another performance characteristic, such as left ventricular contractility. Such blending may include finding an arithmetic mean, geometric mean, or weighted mean of two or more proposed atrio-ventricular delay intervals.
