description An apparatus effectively removes after potential occurring after a electrical pulse is delivered in a cardiac rhythm management system such as a pacemaker system or cardioverter/defibrillator system having an electrode used for both sensing electrical activity of the heart and carrying the electrical pulse to the heart and a sense amplifier for detecting the electrical activity from the electrode. The apparatus includes a lowpass filter coupled to the electrode to filter the sensed electrical activity. A highpass filter is coupled between the lowpass filter and the sense amplifier to further filter the electrical activity passed from the lowpass filter. Equilibrium circuitry is included to allow passive filter components of the lowpass filter and the highpass filter to return to an equilibrium state following delivery of the electrical pulse.
