External pacemaker with an electrode temporarily connectable to a heart and coupled via a plug connector

An external pacemaker (1) comprising at least one electrode (2, 2a, 2b, 2c, 2d) which is temporarily connectable to a heart and at a distal end (3) of which is arranged at least one active region (6) which makes contact with tissue (4) of the heart (5) of a patient in a position of use, the electrode (2, 2a, 2b, 2c, 2d), in the position of use, is joinable or joined to the external pacemaker (1) by a proximal end (7) of said electrode via at least one plug connector, including a contact pin (8, 8a) and a plug socket (9), for transmitting stimulation pulses from the external pacemaker (1) to the heart (5) of the patient, and the electrode (2, 2a, 2b, 2c, 2d), at least at an active region (6) thereof which makes contact with the tissue of the heart (5), has a surface area large enough for transmission or emission of a defibrillation and/or cardioversion pulse, and the contact pin (8) of the plug connector has a first and a second electrical contact portion (11, 12) and the plug socket (9) of the plug connector, in a manner matching the contact pin, has a first and a second electrical mating contact (13, 14), and the two contact portions (11, 12) or the two mating contacts (13, 14) of that part of the plug connector which is arranged at the external pacemaker (1) are wire-able or wired differently, such that one of the two contact portions (11, 12) or mating contacts (13, 14) is provided for transmitting stimulation pulses and the other of the two contact portions (11, 12) or mating contacts (13, 14) are provided for transmitting at least one of defibrillation or cardioversion pulses to the electrode (2, 2a, 2b, 2c, 2d), and wherein the external pacemaker (1) is at least one of connected to a defibrillator and/or cardioverter, contains a defibrillator and/or a cardioverter, or is designed for emitting defibrillation and/or cardioversion pulses.
