Abstract
A ventricular assist system including an implantable rotary pump, a pump drive circuit for supplying power to the pump, and a signal processing circuit receiving one or more electrophysiological signals and one or more physiological signals of the subject. The signal processing circuit is operable to receive inputs from the one or more electrophysiological sensors and the physiological sensor, and determine the presence or absence of a non-normal sinus cardiac rhythm condition based on the input from the electrophysiological sensors. In the presence of a non-normal sinus rhythm, the circuit operates the pump in a modified mode of operation. In the absence of a non-normal sinus rhythm, the circuit operates the pump in a normal mode of operation. In either case, the circuit controls the power to the pump and/or speed of the pump based on the input from the physiological sensor and the mode of operation.
