Details.
Insertion of a small computer-like defibrillator device and three-lead system to respond to and treat rapid heart rhythms. The device can also treat slow heart rhythms like a pacemaker and may help the heart chambers pump more effectively. The procedure involves light sedation and monitoring, lead insertion and testing, connecting and programming the device, and an overnight hospital stay. Surgery usually takes 2 to 4 hours, with hospitalization varying from 1 to 2 days.
