Abstract

The present case report presents two cases in which automatic threshold measurement features in an implantable cardiac defibrillator and in a CRTD act proarrhythmic by inducing polymorphic ventricular arrhythmia. By programming these features off the problem was solved. The mechanisms seem to be different from previously reported proarrhythmic interactions from such device features.

摘要

本病例报告介绍了两例病例，其中植入式心脏除颤器和心脏再同步化治疗除颤器（CRTD）中的自动阈值测量功能通过诱发多形性室性心律失常而发挥促心律失常作用。通过关闭这些功能，问题得以解决。其机制似乎与先前报道的此类设备功能的促心律失常相互作用不同。
