title: A Soviet nuclear pacemaker.
abstract: A Soviet nuclear pacemaker is described. It is a large VOO bipolar pacemaker, probably nonprogrammable. It has unique electrode connectors. No isotope leak or excessive radiation hazard was detected. Because we had no knowledge of its end-of-life markers and because of the impossibility of assuming long-term safety, the device was removed.
