The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a new therapeutic option for patients at risk of sudden cardiac arrest. The device uses a pulse generator implanted in the lateral thoracic region and a tunneled subcutaneous electrode. Benefits of this configuration include the preservation of venous access and reduction in the risk of systemic infection, vascular injury, and lead failure. Clinical trials suggest that the device effectively senses, discriminates, and converts both spontaneous and induced ventricular tachycardia and ventricular fibrillation episodes with minimal complications. The S-ICD represents a novel implantable cardioverter-defibrillator configuration that may provide reliably effective therapy for malignant tachyarrhythmias.
皮下植入式心脏复律除颤器（S-ICD）是心脏骤停风险患者的一种新的治疗选择。该设备使用植入胸外侧区域的脉冲发生器和经隧道的皮下电极。这种配置的优点包括保留静脉通路以及降低全身感染、血管损伤和导线故障的风险。临床试验表明，该设备能有效感知、鉴别并转复自发和诱发的室性心动过速及心室颤动发作，且并发症极少。S-ICD代表了一种新型的植入式心脏复律除颤器配置，可为恶性快速心律失常提供可靠有效的治疗。
