Abstract
In one embodiment, an electrical activity measurement system includes a catheter to be inserted into a body part and including at least one electrode, signal processing circuitry coupled to receive an intracardiac electrogram (IEGM) signal from the at least one electrode and process the IEGM signal for output to a recording apparatus via a cable, which picks up surrounding electrical noise, and feedback circuitry configured to receive at least some of the electrical noise picked up by the cable, and provide a feedback signal indicative of the received electrical noise to the signal processing circuitry, which is configured to compensate at least partially for the electrical noise, which is not yet in the IEGM signal but will be added to the IEGM signal in the cable, responsively to the feedback signal to produce a noise-compensated IEGM signal for output to the recording apparatus via the cable.
