近十年充血性心力衰竭(CHF)死亡者明显增高,在美国每年有200万患者,死亡在20万以上。本文综述在CHF中室性心律不齐和预后之间的关系,病理生理及流行病学。一、病理生理:最近发现室性心律失常在CHF中常见,但发病机理了解较少。半数以上CHF者缺血性心脏病,但不等于心肌缺血必导致心律失常。在缺血与非缺血性心脏病心室节段性运动异 In the past decade, the number of deaths from congestive heart failure (CHF) was significantly higher. In the United States, there are 2 million patients each year, with more than 200,000 deaths. This article reviews the relationship between ventricular arrhythmias and prognosis in CHF, pathophysiology and epidemiology. First, the pathophysiology: Ventricular arrhythmias recently found in CHF common, but less understanding of the pathogenesis. More than half of CHF ischemic heart disease, but not equal to myocardial ischemia will lead to arrhythmia. In ischemic and non-ischemic heart disease segmental ventricular segmental movement
