Key result
An initial appropriate ICD shock induced persistent cellular repolarization abnormalities, resulting in T-wave oversensing that triggered 84 inappropriate shocks and rapid battery depletion.

An appropriate ICD shock may induce persistent cellular repolarization abnormalities, leading to T-wave oversensing, multiple inappropriate shocks, and rapid battery depletion.
Campana (2014) conducted a case report in T-wave oversensing and inappropriate ICD shocks (n=1). Implantable Cardioverter Defibrillator (ICD) was evaluated on Inappropriate shocks and battery depletion. An initial appropriate ICD shock induced persistent cellular repolarization abnormalities, resulting in T-wave oversensing that triggered 84 inappropriate shocks and rapid battery depletion.
