ABSTRACT:
A heart pacemaker electrode for stimulating and detecting heart voltages, has an electrode head at the distal, heart-proximate end, which functions to both stimulate the heart by supplying pulses thereto, and to sense heart activity. The surface of the electrode head is divided into portions which, although electrically connected, exhibit different impedances. Once portion has a lower impedance, which primarily functions for stimulating the heart, and the other portion has a higher impedance which functions in combination with the portion of lower impedance during sensing. The electrode head thus in totality exhibits a low impedance for stimulating the heart, permitting a high current density to be achieved, while exhibiting an overall high impedance for sensing.
