Routine defibrillation threshold testing (DFT) of transvenous implantable defibrillators (ICDs) has largely been in decline. In patients with non-transvenous ICDs that utilize subcutaneous and pleural ICD leads, serial DFT testing can detect a significant number of failures. Data about the utility of follow-up defibrillation safety margin testing (DSM) testing in pediatric patients and young adults with an epicardial ICD are lacking.

常规随访除颤安全裕度测试在心外膜植入式心脏复律除颤器年轻患者中的实用性

经静脉植入式除颤器 (ICD) 的常规除颤阈值测试 (DFT) 已大幅下降。对于使用皮下和胸膜 ICD 导线的非经静脉 ICD 患者，连续 DFT 测试可以检测到大量故障。目前缺乏关于使用心外膜 ICD 的儿科患者和年轻人进行后续除颤安全裕度测试 (DSM) 测试的效用的数据。
