Abstract
An implantable cardiac stimulation device discriminates between noise and an arrhythmia sensed in a heart. A first sensing circuit generates a first signal representing electrical activity sensed in a first location of the heart and a second sensing circuit generates a second signal representing electrical activity sensed in a second location of the heart. The first and second locations are spaced apart and located in respective different corresponding chambers or the same chambers of the heart. A comparison circuit then compares the first and second signals to provide a comparison factor. A control circuit then determines from the comparison factor if noise is sensed or if an arrhythmia is being sensed.
