A medical electrode intended for short term use has a disposable electrode pad provided with a socket and a reusable electrode conductor which is attached to a lead wire and which has a ridged body adapted to enter and be retained by the socket. The pad includes a pair of spaced foam sheets with patient-contacting adhesive layers on their lower surfaces. An electrolyte gel matrix, preferably formed from conductive adhesive urethane hydrogel, is located between the foam sheets. The socket is formed in a relatively stiff socket plate that overlies the gel matrix and the foam sheets. The socket includes a bore located over the gel matrix shaped to receive the electrode conductor, which is slightly larger than the bore, and may optionally include outwardly extending slits projecting from the bore. A method of manufacturing a strip of the electrode pads on a release liner on a continuous basis is disclosed. In a modification for longer term monitoring uses, the electrode pads are constructed to confine the gel matrix to avoid gel dry out and the socket and the conductor are provided with a cooperating key and keyway for restraining relative movements therebetween.
