Title: Cardiac monitoring electrode apparatus and method

Abstract: An ECG electrode and method of making and using such. The electrode can have a domed electrode element attached to a housing containing an interface disk to which the concave side of the domed electrode connects. Within the housing a signal lead wire has one end attached to the non-skin-contacting side of the dome and another end connected to a signal transition circuit and a buffer amplifier circuit. The domed electrode element can be made by forming a metal disk into a dome and providing an oxide layer over the convex surface of the dome. The convex surface of the domed electrode can ensure reliable ECG signal acquisitions with lower radial forces generally than other electrode types, when positioned adjacent the skin of the patient and when coupled to cardiac activity monitoring equipment and a defibrillator for cardiac sensing capabilities.
