Abstract:
1. A device for monitoring cardiac function, comprising: a. a single multi-axis acceleration sensor configured for disposition within the coronary sinus; b. wherein the acceleration sensor is configured to characterize left ventricular function by simultaneously monitoring both cardiac vibration corresponding to mitral regurgitation and left ventricular longitudinal displacement motion; c. a circuit implemented in hardware or software, or both, for receiving signals indicative of left ventricular function including signals corresponding to cardiac vibration caused by mitral regurgitation and signals corresponding to left ventricular longitudinal displacement motion, the circuit further mathematically singly integrating the received signals to obtain velocity information about left ventricular function and the circuit further mathematically doubly integrating the received signals to obtain displacement information about left ventricular function, wherein the single and double integrations are performed using only data from the single multi-axis acceleration sensor.
