A method and apparatus for cardioverter/pacemaking utilizing neurosensing. The invention utilizes the baroreceptor nerves found in the body. A neurosense electrode (12) is placed around the carotid sinus nerve (10) and a sense amplifier with automatic gain control and an integral band pass filter (16) provides a frequency-to-voltage converter (20) with a frequency proportional to the stimulus received from the carotid sinus nerve (10). The voltage from the frequency-to-voltage converter (20) is sent to the analog-to-digital converter (24) where it is bussed to a microprocessor (28). The microprocessor (28) then drives a pacing lead (38) and in the presence of a cardiac signal the microprocessor (28) provides a cardioverting signal to the cardioverting lead (49) if ventricular arrhythmia is sensed. The microprocessor (28) also drives (30) a telemetry coil and receives ventricular information from the ventricular sensing lead (42). <IMAGE> |
