Abstract
To prevent crosstalk between atrial and ventricular bipolar cardiac pacer leads, separate input/output circuits for the two channels are powered by respective isolated capacitors. In one embodiment, the capacitors are resistively coupled to the pacer battery for continuous charging. In another embodiment, one side of each capacitor is normally disconnected from the pacer battery. Charging switches momentarily connect one or the other capacitor directly to the battery in response to the output of the corresponding sense amplifier.
