Abstract

A system and apparatus for detecting electrode faults in a physiological activity acquisition system or device. The system includes at least one signal sensing electrode attached to the subject and a signal processor coupled to the at least one signal sensing electrode. The signal sensing electrode senses a combined signal from the subject. The combined signal has an activity portion and a carrier portion. The signal processor receives the combined signal from the electrode. The signal processor processes the combined signal and generates a noise-redeuced ECG and an electrode fault signal, if an electrode fault exists.
