埋藏式心脏复律除颤器患者术后电风暴的预防和处理

电风暴最初提出于90年代,是指在一段相对较短的时间范围内,出现多次室性心动过速(室速)/心室颤动(室颤)发作。2006年《室性心律失常的诊疗和心脏性猝死预防指南》(ACC/AHA/ESC)定义的电风暴是指24h内自发的室速/室颤≥2次,并需要紧急治疗的临床症候群[1]。埋藏式心脏复律除颤器

Prevention and Treatment of Electrical Storm in Patients with Implanted Cardioverter Defibrillator

The term "electrical storm"(ES)in patients with an implantable cardioverter defibrillator(ICD)indicates a state of cardiac electrical instability manifested by several episodes of ventricular tachyarrhythmias(VTs)and ventricular fibrillation within a short time.In this article,we have reviewed the definition,incidence,triggers,treatment,prevention and prognosis of ES in patients with ICD.The role of ICD programming such as antitachycardia pacing(ATP)is highly effective,equally safety,and improves the quality of life.ATP may be the preferred fasicular ventricular tachycardia therapy in most ICD patients.The reduction of the elevated sympathetic tone by beta blockers is one of the key intervention in ES.The combination of amiodarone therapy is determined by the individual condition of patients.ES seems to have an impaired prognosis and frequently leads to hospitalization.Long-term prognostic implications of ES are unclear.
