Description
Diogo Fernandes and co-authors track defibrillator battery life in a 2023 real-world study. Implanted defibrillators guard against fatal heart rhythms, but hard data on how long modern batteries last were scarce. The team follows 351 patients at one center who received devices from five makers over six years.
Median battery life reaches about eleven years, shorter for dual-chamber models. After five years nearly all devices remain in service, matching maker projections. A quarter of patients need a replacement in the study window, mostly for drained batteries. Two brands show earlier battery-driven replacement than others. The authors say the results broadly match industry claims.
