  • ECG electrode contact quality measurement system
    Patent number: 8086300
    Abstract: A system and method are provided for generating output signals indicative of contact quality of a plurality of electrodes coupled to a patient. A signal generator coupled to a reference electrode injects an alternating signal into the patient. A plurality of differential amplifiers, each coupled to a respective one of the plurality of electrodes to detect an input signal from the patient, are operable to output a respective output signal in response to a respective input signal. The output signal generated by the respective differential amplifier is indicative of contact quality for the respective electrode.
