慢型克山病并发室性早搏对预后的意义——附578例分析

本文就578例慢型克山病患者伴发的室性早搏(室早)进行了分析,其总检出率为45.2%,心功能越差发生率越高。室早“良性者”占71.6%,“恶性者”占28.4%,异位起搏点在左室者占65.1%,右室占26.1%,双室为8.8%。对死亡病例,分为室早并发组和未发组对比分析?发现并发室早的病例近期死亡率高、远期存活率低,存活时间短。

Significance of prognosis of chronic Keshan disease with ventricular extrasystole

This paper analyses chronic Keshan disease with ventricular extrasytole in 578cases.The result shows the rate of ventricular extrasystole is 45.2 per cent amongpatients with Keshan disease.The worse the heart funation is,the higher therate of ventricular extrasystole.The innocent ventricular extrasystole is 71.6 per centand fatal ventricular extrasystole 28.4 per cent among ventricular extrasystoles.Theorigin of extrasystole is 65.1 per cent in the left ventricle,26.1 per cent in rightventricle and 8.8 per cent in both ventricles.The analysis of the cases of deathin two groups,(one of ventricular extrasystole and the other of non-ventricularextrasystole)shows that the mortality of patients with ventricular extrasystoleis higher in the short period and the survival rate is lower in the long periodwith a short surviving period.
