A 46-year old man was implanted with a totally subcutaneous implantable defibrillator, after having a documented episode of cardiac arrest due to idiopathic ventricular fibrillation. During the 4‑month follow-up, an episode of inappropriate triple counting due to P‑ and T‑wave oversensing was detected. Although preoperative screening, high detection rates, and the INSIGHT(TM) discrimination algorithm have reduced the incidence of oversensing-related implantable cardioverter defibrillator (ICD) shocks, continuous evaluation of appropriate sensing vectors at rest, during positional maneuver, and exercise, seems to be mandatory at each follow-up visit.
一名46岁男性因特发性心室颤动发生心脏骤停且有记录，之后植入了完全皮下植入式除颤器。在4个月的随访期间，检测到因P波和T波感知过度导致的不适当三重计数事件。尽管术前筛查、高检测率以及INSIGHT(TM)鉴别算法已降低了与感知过度相关的植入式心脏复律除颤器(ICD)电击发生率，但在每次随访时，似乎都必须对静息、体位变动和运动时的适当感知向量进行持续评估。
