### Learning objectives Ventricular arrhythmias present in many ways, ranging from isolated premature beats to sustained ventricular tachycardia (VT). They can occur in patients with or without structural heart diseases and at a wide spectrum of ages. Knowledge of acute management of sustained VT is therefore a priority for all cardiologists, as confirmed in Section 2.20 of the European Society of Cardiology (ESC) Core Curriculum in Cardiology. This article will provide the latest overview on the management of an intimidating and life-threatening condition: VT storm. It will also address the unique challenges posed by the increased use of remote monitoring in the routine care of patients with animplantable cardioverter defibrillator (ICD). According to the latest consensus guidelines, VT is defined as cardiac arrhythmia of ≥3 consecutive complexes originating in the ventricles at a rate of >100 beats per minute (cycle length: <600 ms).1 Sustained VT is defined as that lasting more than 30 s or requiring an intervention prior to that due to haemodynamic instability. VT storm is defined as three or more episodes of sustained VT within a 24-hour period, each requiring termination by an intervention such as cardioversion, antitachycardia pacing (ATP) or defibrillation.2 In patients without an ICD, it has been further defined as (1) VT recurring soon after (within 5 min) termination of another VT episode; and (2) sustained and non-sustained VT resulting in a total number of ventricular ectopic beats greater than sinus beats in a 24-hour period.3 In patients with an ICD, the definition is prone to (1) underdetection if the rate of the device at which it starts counting beats …

室性心动过速风暴的处理

### 学习目标 室性心律失常以多种方式存在，从孤立性早搏到持续性室性心动过速 (VT)。它们可能发生在有或没有结构性心脏病的患者身上，而且年龄范围很广。因此，正如欧洲心脏病学会 (ESC) 心脏病学核心课程第 2.20 节所证实的那样，了解持续性 VT 的急性管理知识是所有心脏病专家的优先事项。本文将提供有关管理令人生畏和危及生命的情况的最新概述：VT 风暴。它还将解决在植入式心脏复律除颤器 (ICD) 患者的常规护理中越来越多地使用远程监控所带来的独特挑战。根据最新的共识指南，VT 被定义为 ≥ 3 个连续复合波以每分钟 > 100 次（周期长度：<600 ms）的速率起源于心室的心律失常。1 持续性 VT 被定义为持续超过 30 秒或需要事先干预由于血流动力学不稳定。VT 风暴定义为 24 小时内发生 3 次或更多持续性 VT，每次都需要通过心脏复律、抗心动过速起搏 (ATP) 或除颤等干预措施终止。2 在没有 ICD 的患者中，它被进一步定义为(1) 在另一次 VT 发作终止后不久（5 分钟内）VT 复发；(2) 持续和非持续 VT 导致 24 小时内室性异位搏动总数大于窦性搏动 3。
