Abstract
Systems and methods are provided for adjusting atrioventricular timing of a cardiac resynchronization therapy device, based upon multi-modal sensory data. In one particular embodiment, one or more acoustic signals are processed and categorized into certain cardiac-related mechanical events. Impedance waveforms are obtained from implanted electrodes and analyzed to identify certain valvular events. The acoustic and impedance data is analyzed to optimize AV timing and improve cardiac performance.
