Abstract
Interchannel crosstalk in an existing dual channel pacer designed for bipolar leads is reduced by inserting a switching circuit between the pacing leads and the pacer terminals. In one embodiment, in each channel an isolation resistance and buffer amplifier in series with the lead electrodes, respectively, are shunted during stimulation. In another embodiment, the lead electrodes are connected to a pair of differential amplifiers which are bypassed during stimulation on a given channel.
