皮下埋藏式心脏转复除颤器(ICD)(S-ICD)技术是预防心源性猝死(SCD)的新尝试,避免了传统静脉ICD的导线并发症,适用于导线并发症发生率高、无起搏指征、预期生存时间长的年轻患者。众多临床研究证实了S-ICD在治疗SCD中的有效性、安全性。S-ICD系统主要由脉冲发生器、皮下电极、体外程控仪构成。S-ICD存在延迟放电、不恰当放电、高能放电、无起搏功能、兼容性等尚存争议的问题。S-ICD在一定适应证范围内有潜在大的应用前景。
The subcutaneous implantable cardioverter defibrillator (ICD) technique is a new attempt to prevent sudden cardiac death (SCD). It avoids the wire complication of traditional venous ICD and is suitable for the high incidence of lead complications. No signs of pacing, long-expected survival of young patients. Many clinical studies have confirmed the S-ICD in the treatment of SCD in the effectiveness and safety. S-ICD system mainly consists of pulse generator, subcutaneous electrodes, in vitro program-controlled device. S-ICD has some controversial issues such as delayed discharge, improper discharge, high-energy discharge, non-pacing function and compatibility. S-ICD in a certain range of indications have potential applications.
