An electrode for electrocardiographic examinations comprises a substantially rigid back piece, an electrode plate joined substantially non-movably to the back piece and a resiliently deformable sealing component interposed between the electrode plate and the back piece. When the electrode is not applied to the patient, flow of ambient air to a vacuum chamber in the back piece is blocked or restricted. Upon applying the electrode to the patient\s skin, an outer sealing rim in engagement with the patient\s skin forms a seal between the patient\s skin and the back piece, thereby to define a vacuum chamber between the back piece and the patient\s skin. The vacuum holds the electrode plate firmly in engagement with the patient\s skin.

An electrode for electrocardiographic examinations and the like comprising a substantially rigid back piece having a chamber, means for connecting the chamber to a vacuum source, an electrode plate joined substantially non-movably to the back piece and having an electrically conductive frontal surface adapted to be connected to a measuring device and adapted to engage the skin of a patient being examined, and a sealing component interposed between the electrode plate and the back piece and having a central portion in sealing engagement with the back piece externally of the back piece chamber and a resiliently deformable sealing ring portion outwardly of the central portion that includes an outer sealing rim engageable with the skin of a patient to be examined and with the back piece, the sealing ring portion being adapted to be resiliently deformed toward the back piece by the force on the outer sealing rim when the electrode is pressed toward the patient\s skin, whereby a vacuum is generated in a zone defined by the back piece, the outer sealing rim and the patient\s skin inwardly of the outer sealing rim, thus firmly to engage and hold the electrode plate against the patient\ s skin by a force generated by the vacuum that displaces the back piece, the central portion of the sealing component, and the electrode plate toward the patient\s skin upon deformation of the sealing ring portion of the sealing component, and means for restricting the flow of air to the back piece chamber when the electrode is not in place on the patient.
