1. A method for dynamic device based AV delay adjustment, the method comprising:
providing electrodes configured to be located proximate to an atrial (A) site and a right ventricular (RV) site;
utilizing one or more processors for:
detecting an atrial paced (Ap) event or atrial sensed (As) event;
measuring an AV interval corresponding to an interval between the Ap event or the As event and a sensed ventricular (Vs) event;
automatically dynamically adjusting a first AV delay based directly on the measured AV interval to define a corresponding one of a paced or sensed AV delay (AVDp or AVDs);
identifying a scale factor, the scale factor representing a relation between a base As-Vs interval and a base Ap-Vs interval;
calculating a second AV delay by scaling the first AV delay based on the scale factor to define a corresponding other one the AVDp or AVDs; and
managing a pacing therapy, utilized by the IMD, based on the AVDp and AVDs.
