In a cardioverter/defibrillator system, an electrical circuit includes an
energy storage device, an output circuit for controlling delivery of pulse
therapy from the energy storage device to a patient, and a sensing circuit
coupled across the patient to sense the patient's heart signal. The output
circuit may be in the form of an H-bridge switching circuit wherein a pair
of switches of the output circuit is simultaneously turned on to discharge
residual voltage across the patient that remains after delivery of pulse
therapy. Thus, interference with sensing of the patient's heart signal is
avoided.
