The subcutaneous implantable defibrillator (S-ICD) has become an established tool for the prevention of sudden cardiac death. Based on its detection properties, the S‑ICD is essentially dependent on correct morphology discrimination of the QRS complex and avoidance of potential T‑wave sensing. We report on a patient who experienced multiple inappropriate S‑ICD shocks due to T‑wave oversensing in the setting of new onset of right bundle branch block. Strategies for the optimisation of the device programming are discussed.
皮下植入式除颤器（S-ICD）已成为预防心脏性猝死的既定工具。基于其检测特性，S-ICD本质上依赖于对QRS波群的正确形态辨别以及避免潜在的T波感知。我们报告了一名患者，该患者在新发右束支传导阻滞的情况下因T波过度感知而经历了多次不适当的S-ICD电击。文中讨论了优化设备编程的策略。
