慢性充血性心力衰竭(CHF)患者复杂室性心律失常(CVA)和猝死的发生率较高。从理论上讲,CHF患者应当使用抗心律失常药物预防致死性CVA,然而前瞻性随机试验至今缺如,回顾性分析的结论又不一致。CHF患者使用抗心律失常药物的主要危险性在于:心室泵血功能的进一步减退,CVA的恶化甚至危及生命。现有资料表明,CHF患者
Patients with chronic congestive heart failure (CHF) have a higher incidence of complicated ventricular arrhythmia (CVA) and sudden death. In theory, CHF patients should use antiarrhythmic drugs to prevent lethal CVA, but prospective randomized trials have so far lacked, and the conclusions of retrospective analysis are inconsistent. The major risks of anti-arrhythmic drugs in patients with CHF are the further diminution of ventricular pumping function, the worsening of CVA, and even life-threatening conditions. Available data show that CHF patients
