慢性心衰病人出现无症状室性心律失常和猝死非常常见,但该病人的频发,复杂性室性心律失常与猝死是缺乏联系的。因为,1.复杂室性心律失常可能是左心室衰竭的非特异性表现。长期随访发现,伴有持续性室性心动过速的轻度心衰患者病情大多进行加重,而非猝死。2.猝死的原因不是恶性心律失常,患有冠脉疾病的心衰患者其猝死的最常见原因是急性心肌缺 Asymptomatic ventricular arrhythmias and sudden death are very common in patients with chronic heart failure, but the frequent, complex ventricular arrhythmia in this patient is not linked to sudden death. Because, 1. Complex ventricular arrhythmias may be a nonspecific manifestation of left ventricular failure. Long-term follow-up found that mild heart failure patients with persistent ventricular tachycardia mostly aggravate the condition, rather than sudden death. 2. The cause of sudden death is not a malignant arrhythmia, coronary heart disease patients with heart failure, the most common cause of sudden death is acute myocardial infarction
