T-wave oversensing can be a serious problem that often results in inappropriate device therapy. We report here a patient with binge alcohol use who received multiple, inappropriate ICD shocks due to T-wave oversensing from repolarization changes induced by acute alcohol intoxication and no other relevant metabolic derangements. Following recovery from his alcohol intoxication a few days later, the T-wave amplitude decreased so the device no longer inappropriately sensed or delivered therapies. This case represents an uncommon, but reversible, cause of T-wave oversensing that should be considered before more aggressive measures are taken to correct the abnormality.
T波感知过度可能是一个严重问题，常常导致不适当的设备治疗。我们在此报告一名大量饮酒的患者，其因急性酒精中毒引起的复极改变导致T波感知过度，且无其他相关代谢紊乱，从而接受了多次不适当的植入式心律转复除颤器（ICD）电击。几天后，他从酒精中毒中恢复，T波振幅降低，因此该设备不再不适当感知或发放治疗。该病例代表了一种罕见但可逆的T波感知过度原因，在采取更积极措施纠正异常之前应予以考虑。
