A cardiac device helps control irregular heartbeats to protect against heart rhythm disorders. One of the most commonly used cardiac devices is a pacemaker, which produces electrical stimuli to the heart to help it maintain rhythm. An Implantable Cardioverter Defibrillator (ICD) is used to assist the heart's ventricles to restore their capacity after an irregularity. The surgery to implant these devices is quick and patients are often discharged soon after the procedure is completed.
