Abstract
Endocardial system and method in which noise and artifacts introduced by a simulator are decoupled from a recorder by connecting the stimulator to the electrodes used for pacing and recording only when it is necessary to do so. At other times, the stimulator is disconnected, and low level signals are recorded without interference from the stimulator. In one embodiment, the stimulator is connected only during the time the pacing pulse is being delivered. In another, a stimulator which delivers pacing pulses in response to intrinsic activation of tissue at the pacing site is connected during delivery of a pacing pulse, disconnected during the measurement period which follows, and then reconnected so that it can sense further intrinsic activity and deliver another pacing pulse.
