SYSTEM AND METHOD FOR DETERMINING CARDIAC EVENTS USING LAP SIGNALS
摘要
Cardiac valve events are monitored by recording a left atrial pressure (LAP) representing signal using an implantable pressure sensor (50). The LAP signal is processed in order to generate a derivative LAP signal representative of the first time derivative of the LAP signal. The opening of the aortic valve of the heart is then identified to coincide in time with a minimum in the derivative LAP signal following ventricular depolarization in a cardiac cycle.
