Leads, External Cardiac Pacemaker, Transesophageal
Definition : External cardiac pacemaker invasive leads designed to conduct electrical pacing signals from the pulse generator of an external pacemaker through the esophagus and into the heart. 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. Transesophageal 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 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).
