An R-wave detection system includes an electrode for placement in close proximity to or in contact with a heart to sense electrical activity of the heart. A signal processor is in communication with the electrode, and is responsive to receipt of the analog signal from the electrode to condition the signal to account for noise and far-field effects. The system is operative to determine whether the conditioned signal exceeds a dynamic threshold value and, if so, the system generates a synchronization pulse to indicate the rising edge of an R-wave.

Digital ECG detection system

A cardiac support system includes a ventricular assist device adapted to be extended over a portion of a patient's heart to assist the ventricles of the heart to properly contract. One or more stimulating electrodes are mounted on the ventricular assist device in selected locations such that when the ventricular assist device is extended over the heart, the stimulation electrodes are in close proximity to the surface of the heart. The system further includes one or more external pick-up electrodes that receive externally applied energy and conduct that energy to the one or more stimulating electrodes via conductive leads. The external pick-up electrodes may be mounted on the outer surface of the ventricular assist device, or can be located at some other location inside the patient's body. The externally-applied energy will typically be supplied by standard defibrillation paddles located outside of the patient's body. In place of the pick-up electrodes, the stimulating electrodes can be wired directly to, respectively, a source of electrical energy and a ground plate.
