Abstract
A method and system for applying therapeutic electrical pulses to the heart includes a plurality of spaced apart electrodes. Each electrode in electrical communication with a pulse generator and are operative to deliver at least one energy pulse to a patient'"'"'s heart. Sensors and electrical communication with a controller are operative to detect an abnormal rhythm in the patient'"'"'s heart and transmit a signal to a controller to indicate an abnormal rhythmic condition. The controller is configured to receive the abnormal rhythmic signal from the sensor and cause the pulse generator to emit a sequence of spatially and temporally distinct pulses through the electrodes, each pulse passing through at least one of the electrodes.
