急性冠脉综合征后室性心律失常性电风暴,是指心室颤动(VF)或血流动力学不稳定室性心动过速(VT)在24 h内反复发作≥20次或≥4次/h,通常需要电除颤或电复律中止VF或VT,绝大多数ACS后电风暴见于急性心肌梗死后,多见于前降支或右冠近端闭塞后,可在血运重建后发生。
Ventricular arrhythmia after acute coronary syndrome refers to ventricular fibrillation (VF) or hemodynamic unstable ventricular tachycardia (VT) repeated within 24 h ≥ 20 times or ≥ 4 times / h, usually require defibrillation or cardioversion to suspend VF or VT, the vast majority of ACS after the electrical storm seen in acute myocardial infarction, more common in the anterior descending branch or right coronary proximal occlusion, can occur after revascularization.
