An active low impedance electrode (20) employing an electrical activity sensor (21) connected to a voltage sense contact (22), a current flow contact (23) and an active electrode coupler (24). In operation, responsive to the voltage sense contact (22) and the current flow contact (23) being attached to the anatomical region (13) of the patient, the electrical activity sensor (21) controls a directional flow of a sensor current between the electrical activity sensor (21) and the anatomical region (13) to establish an equivalence between a patient voltage at voltage sense contact (22) and a sensor voltage at active electrode coupler (24), and/or a patient contact impedance between the voltage sense contact (22) and the current flow contact (23) is greater than an active electrode impedance at the active electrode coupler (24). |
