Abstract

Tachycardia detection and therapy algorithms in Implantable Cardioverter-Defibrillators (ICD) reduce, but do not eliminate inappropriate ICD shocks. Awareness of the pros and cons of a particular algorithm helps to predict its utility in specific situations. We report a case where PR logic™, an algorithm commonly used in currently implanted ICDs to differentiate supraventricular tachycardia (SVT) from ventricular tachycardia resulted in inappropriate detection and shock for an SVT, and discuss several solutions to the problem.

摘要

植入式心脏复律除颤器（ICD）中的心动过速检测与治疗算法可减少但不能消除不适当的ICD电击。了解特定算法的优缺点有助于预测其在特定情况下的效用。我们报告了一例病例，其中目前植入的ICD中常用的一种用于区分室上性心动过速（SVT）和室性心动过速的PR logic™算法导致对SVT进行了不适当的检测和电击，并讨论了该问题的几种解决方案。
