Abstract

In one embodiment, a method includes receiving cardiac signal segments responsively to electrical activity sensed by a first sensing electrode in contact with tissue, injecting the cardiac signal segments into a cable, which extends to a recording apparatus, the cable outputting corresponding noise-added cardiac signal segments responsively to noise acquired in the cable, training an artificial neural network to at least partially compensate for electrical noise that will be added to signals in the cable responsively to the received cardiac signal segments and corresponding noise-added cardiac signal segments, receiving a cardiac signal responsively to electrical activity sensed by a second sensing electrode, applying the trained artificial neural network to the cardiac signal yielding the cardiac signal with noise-compensation, which at least partially compensates for noise, which is not yet in the cardiac signal but will be added in the cable, and outputting the cardiac signal with noise-compensation via the cable.
