ABSTRACT:
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.
