摘要

一位 80 岁的患者曾因特发性持续室性心动过速而植入 Rivacor VR-T DX 植入式心脏转复除颤器（ICD Biotronik，德国柏林），后因心悸来到我们的起搏器诊所就诊。心电图（ECG）显示窦性心动过缓，伴有室性异位搏动。心室搏动事件发生时的耦合间期短于预期，表明心室感应不足。这一现象可以用制造商建议的 ICD 默认灵敏度设置来解释。

Functional Ventricular Undersensing After Ventricular Ectopic Beats Due to ICD Dynamic Sensitivity.

An 80-year-old patient, previously implanted for idiopathic sustained ventricular tachycardia with a Rivacor VR-T DX implantable cardioverter defibrillator (ICD Biotronik, Berlin, Germany), came to our pacemaker clinic for palpitations. Electrocardiogram (ECG) showed sinus bradycardia with interpolated ventricular ectopic beats. A ventricular-paced event occurred with a coupling interval shorter than the expected one suggesting ventricular undersensing. The phenomenon can be explained by the default ICD sensitivity setting proposed by the manufacturer.
