<p>A cardiac assist system (10) includes a sensor (12) that is operative to sense the electrical activity of a patient's heart. The sensed electrical activity is processed by a controller (11) to determine the onset of ventricular contraction. A compressive force from a ventricular assist device (17) is applied to the ventricles during at least a portion of the heart's ventricular contraction. The cardiac assist system also includes an electrical stimulating system (14, 15). Thus, in the event the heart begins to fibrillate, the electrical stimulating system is actuated to apply stimulating pulses to the heart.</p> |
