Formatted Abstract/Summary
Tremendous advances have occurred in implanted cardiac device therapy, from the evolution of pacemakers to the modern era of high-voltage defibrillation and resynchronization devices. Advances in the components, integrated circuitry, size, and software of the implantable pulse generator are readily apparent, but the revolutionary progress in the design and manufacture of device leads is often not appreciated. In any device system, the lead is the critical interface linking the pulse generator and the myocardium; it allows for communication of electrical signals from the heart to the pulse generator through the sensing circuitry, and in the reverse direction, it allows for bradycardia pacing or tachyarrhythmia therapy. Although leadless pacing and defibrillation device systems are being actively developed, leads clearly will remain an integral component of device therapy for the foreseeable future.

Whether used for pacing, resynchronization, or defibrillation, and regardless of their internal structural design, all leads contain several common components, including electrodes, conductors, insulators, fixation mechanisms, and connector pins. Defibrillation leads also contain shock coils for the delivery of high-voltage, high-current electrical discharges to terminate ventricular fibrillation. This chapter examines each of these elements as well as the overall design, construction, and evolution of pacemaker and implantable cardioverter-defibrillator (ICD) leads.
