Defibrillators are devices that restore a normal heartbeat by sending an electric pulse or shock to the heart. They are used to prevent or correct an arrhythmia, a heartbeat that is uneven or that is too slow or too fast. Defibrillators can also restore the heart's beating if the heart suddenly stops.

How long does the average person live with a defibrillator?

Conclusions: ICDs continue to have limited longevity of 4.9 ± 1.6 years, and 8% demonstrate premature battery depletion by 3 years. CRT devices have the shortest longevity (mean, 3.8 years) by 13 to 17 months, compared with other ICD devices.

How long do you stay in the hospital after a defibrillator?

The procedure typically takes between one and three hours. Afterward, you'll stay in the hospital for at least 24 hours for recovery and monitoring. You should feel fully recovered within four to six weeks. A doctor can also implant an ICD surgically under general anesthesia.
