Electrodes, Cardiac, External Pacemaker, Transvenous

Definition : External pacemaker electrodes designed to be inserted into the heart through a major vein (e.g., subclavian vein). The electrodes are typically inserted into the venous system through a catheter, or sheath and displaced until they are in direct contact with the heart tissue. These devices typically consist of small size electrodes that deliver a lower quantity of energy than other external pacemaker electrodes due to their direct contact with the heart tissue; transvenous electrodes are usually disposable. Transvenous pacemaker electrodes are only intended for temporary pacing of the heart; they are commonly used after open-heart surgery until the heart recovers, in an emergency until a pacemaker can be surgically implanted, and for cardiac electrophysiological studies.
