室性心动过速（VT）最常见于结构性心脏病患者，可与猝死风险增加相关。室颤的最常见原因是急性冠状动脉缺血，而既往梗死的心肌瘢痕是结构性心脏病患者持续性单形性VT的最常见原因。良性的特发性室性心动过速也可发生在无结构性心脏病的情况下。室性心动过速的治疗包括紧急处理和通过药物和器械治疗预防复发。经过适当选择的VT患者或有VT风险的患者可能是植入式心律转复除颤器的候选人。左心室射血分数最常用于对缺血性或非缺血性心肌病患者进行分层，这些患者有猝死的风险，可能是预防性除颤器的候选者。导管消融术也可以是适当选择的多种形式VT患者的一种选择。本文就室性心动过速的病因、治疗及其与猝死的关系进行讨论。
Ventricular tachycardia (VT), which most commonly occurs in patients with structural heart disease, can be associated with an Increased risk of sudden death. The most common cause of ventricular fibrillation Is acute coronary Ischemia, whereas a myocardial scar from prior infarct Is the most common cause of sustained monomorphic VT In patients with structural heart disease. More benign forms of idiopathic VT can also occur In the absence of structural heart disease. Treatment of VT Involves both emergent management and prevention of recurrence with medical and device therapy. Appropriately selected patients who have experienced VT or those who are at risk of VT may be candidates for an implantable cardioverter-defibrillator. The left ventricular ejection fraction Is most frequently used to stratify patients with either ischemic or nonischemic cardiomyopathy who are at risk of sudden death and may be candidates for a prophylactic defibrillator. Catheter ablation may also be an option for appropriately selected patients with many forms of VT. This article discusses the etiologies and management of VT and Its association with sudden death.
