Abstract
Systems and methods are provided wherein intracardiac electrogram (IEGM) signals are used to determine a set of preliminary optimized atrioventricular (AV/PV) and interventricular (VV) pacing delays. In one example, the preliminary optimized AV/VV pacing delays are used as a starting point for further optimization based on impedance signals such as impedance signals detected between a superior vena cava (SVC) coil electrode and a device housing electrode, which are influenced by changes in stroke volume within the patient. Ventricular pacing is thereafter delivered using the AV/VV pacing delays optimized via impedance. In another example, parameters derived from IEGM signals are used to limit the scope of an impedance-based optimization search to reduce the number of pacing tests needed during impedance-based optimization. Biventricular and multi-site left ventricular (MSLV) examples are described.
