Disclosed is an electrode (10, 60) for placement upon the skin of a patient (12) to deliver electrical pulses from medical electronic equipment (16) to the patient. The electrode includes (10, 60) an electrically conductive layer (24, 74) having a skin-facing side and an upper side. An impedance-decreasing layer (32, 82) is adjacent a substantial portion of the skin-facing side of the conductive layer (24, 74). A substantially electrically nonconductive backing layer (18, 68) is adjacent the upper surface of the conductive layer (24, 74), the backing layer (18, 68) being substantially impermeable to the impedance-decreasing layer (32, 82). A gas-permeable layer (20, 70) is between the backing layer (18, 68) and the conductive layer (24, 74). Finally, a vent (22, 72) is provided for venting gas formed between the impedance-decreasing layer (32, 82) and the conductive layer (24, 74) to the environment.
