Leads, External Cardiac Pacemaker, Endocardial
Definition : Leads designed to conduct electrical pacing signals from the pulse-generating unit of an external cardiac pacemaker to electrodes placed on the internal lining of the heart/heart structures (i.e., endocardial or transvenous leads) through the vasculature. Some leads may also conduct the bioelectric cardiac signals back to the unit. These leads typically consist of flexible wires that are completely isolated except at the electrode tip that makes contact with the heart. Cardiac pacemaker leads are configured according to the pacemaker characteristics and/or the technique used for signal delivery to the heart. A variety of lead systems, including single- and multiple-lead, subcutaneous array, and patch is available. Lead size, connector type, and other characteristics of the leads must be compatible with the pulse generator and the therapy prescribed. Endocardial external cardiac pacemaker leads are used in temporary procedures (e.g., surgery, emergency, electrophysiology studies).
