概述

背景植入式心律转复除颤器(implantable cardioverter-defibrillator, ICD)的应用急剧增加,用以监测单形性或多形性室性心动过速(ventricular tachycardia, VT)/心室颤动(ventricular fibrillation, VF)及提供及时的治疗。由于其迅速终止VT/VF的成功率较高,且多项临床试验的结果显示其可提高生存率,所以对于SCD的二级预防以及某些因为VT/VF有SCD高风险人群的一级预防,通常考虑将ICD植入作为一线治疗选择

Because of its high success rate in terminating ventricular tachycardia (VT) and ventricular fibrillation (VF) rapidly, along with the results of multiple clinical trials showing improvement in survival, implantable cardioverter-defibrillator (ICD) implantation is generally considered the first-line treatment option for the secondary prevention of sudden cardiac death (SCD) and for primary prevention in certain populations at high risk of SCD due to VT/VF. However, there are some situations in which ICD therapy is not recommended, including but not limited to patients with VT/VF from a completely reversible disorder and patients without a reasonable expectation of survival with an acceptable functional status for at least one year.  The main indications for use of an ICD can be divided into two groups:Secondary prevention of sudden cardiac death (SCD) in patients with prior sustained ventricular tachycardia (VT), ventricular fibrillation (VF), or resuscitated SCD thought to be due to VT/VF;Primary prevention of SCD in patients at increased risk of life-threatening VT/VF. Primary prevention — Implantation of an ICD is recommended for the primary prevention of SCD due to life-threatening VT/VF in patients who have received optimal medical management (including use of beta blockers and angiotensin converting enzyme [ACE] inhibitors) yet remain at high risk of SCD, including: Patients with a prior MI (at least 40 days ago) and left ventricular ejection fraction (LVEF) ≤30 percent; Patients with a cardiomyopathy, New York Heart Association (NYHA) functional class II to III, and LVEF ≤35 percent. Patients with a nonischemic cardiomyopathy generally require optimal medical therapy for three months with documentation of persistent LVEF ≤35 percent at that time. Contemporary ICDs have extensive storage and monitoring capacities, the ability to deliver anti-tachycardia pacing (ie, overdrive pacing) to terminate VT, the ability to deliver synchronized and unsynchronized shocks for VT/VF, and the option of bradycardia pacing.

由于其在快速终止室性心动过速(VT)和心室颤动(VF)方面的高成功率,以及多项临床试验显示存活率提高的结果,植入式心律转复除颤器(ICD)植入通常被认为是一线治疗选择二级预防心源性猝死(SCD)和某些人群的初级预防,因为VT / VF导致SCD高危。然而,在某些情况下不推荐ICD治疗,包括但不限于来自完全可逆性疾病的VT / VF患者和没有合理预期存活且具有可接受的功能状态至少一年的患者。使用ICD的主要适应症可分为两组:先前持续性室性心动过速(VT)患者的心源性猝死(SCD)的二级预防,心室颤动(VF)或认为由于VT导致的复苏SCD / VF;对危及生命的VT / VF风险增加的患者进行SCD的一级预防。一级预防 - 对于接受最佳医疗管理(包括使用β受体阻滞剂和血管紧张素转换酶[ACE]抑制剂)但仍保持高水平的患者,由于危及生命的VT / VF导致的SCD一级预防,建议植入ICD SCD的风险,包括:先前MI(至少40天前)和左心室射血分数(LVEF)≤30%的患者;患有心肌病的患者,纽约心脏病协会(NYHA)功能II至III级,LVEF≤35%。非缺血性心肌病患者通常需要3个月的最佳药物治疗,并记录当时持续LVEF≤35%。当代ICD具有广泛的存储和监测能力,能够提供抗心动过速起搏(即过驱动起搏)以终止VT,能够为VT / VF提供同步和非同步电击,以及选择心动过缓起搏。
