Abstract
An apparatus comprises a primary cardiac signal sensing circuit configured to sense at least a first cardiac signal, a secondary cardiac signal sensing circuit configured to sense a secondary cardiac signal, and a control circuit. The control circuit includes a noise detection circuit that has an alignment circuit. The alignment circuit is configured to align a segment of the sensed first cardiac signal with a segment of the sensed secondary cardiac signal. The noise detection circuit configured to determine a number of turns in the first cardiac signal segment, determine a number of turns in the secondary cardiac signal segment, generate an indication of noise in the first and secondary cardiac signals according to the determined number of turns, and provide the indication of noise to a user or process.
