Abstract
Systems and methods of performing rhythm discrimination within a patient's body using sensed hemodynamic signals are disclosed. The method can include the steps of receiving an electrical activity signal from an electrode located within or near the heart, detecting an event of the heart based on the received electrical activity signal, sensing one or more mechanical measurements using a sensor located within the body, analyzing a mechanical activity signal received from the sensor, and confirming the type of event based on the mechanical and electrical activity signals. The sensor can comprise a single pressure sensor configured to sense both atrial and ventricular activity within the heart.
