【摘要】 目的 观察胺碘酮对扩张型心肌病合并室性心律失常的QT离散度(QTd)及预后影响。方法 选择的患者予以可达龙治疗8周，并比较治疗前后室性心律失常疗效及QTd的变化。结果 治疗后室性心律失常均明显减少，有效率85.2%，QTd胺碘酮明显减少，由(65.06±11.24)ms减至(33.9±16.2)ms(P<0.01)。结论 胺碘酮能有效减少扩张型心肌病室性心律失常，而且使患者QTd明显减少，改善患者的预后。

    【Abstract】 Objective To investigate the influence of amiodarone on QT Dispersion (QTd)in patients with dilated cardiomyopathy and ventricular arrhythmias.Methods Observing the values of QTd and effect on ventricular arrhythmias was compared before and after the treatment with amiodarone 8 weeks in patients with dilated cardiomyopathy and ventricular arrhythmias.Results After 8 week of treatment , ventricular arrhythmias was remarkable reduced , QTd have decreased from(65.06±11.24)ms to (33.9±16.2)ms (P<0.01).Conclusion Amiodarone is effective on dilated cardiomyopathy and ventricular arrhythmias and can reduce QTd. ......
