Abstract
A circuit for contact impedance monitoring in ECG is presented. An ac current in the same frequency band as the ECG signal is used for the measurement. This makes the measurement independent of polarization potentials and gives the correct weight to the impedances in the skin-to-electrode junction. The measurement of the contact impedance is made continuously during ECG monitoring and causes no interference in the ECG signal.
