Abstract: An electrode belt assembly for positioning an electrically conductive electrode against the body member of a patient, particularly an infant, includes a flexible web belt having a plurality of apertures therein and an electrode pad assembly that can be selectively positioned in a desired aperture. The electrode pad assembly includes a disk pad having a receptacle that is received within a selected aperture in a form fit and a lead probe assembly receivable within the receptacle. The receptacle presents a probe receiving channel oriented generally parallel to the surface of the belt. The engagement of the disk pad and lead probe assembly with the opposed surfaces of the belt, together with the form fit of the receptacle within a selected aperture, provide for a secure positioning of the electrode pad on the belt.
