摘　　要：目的:探讨68例肺心病合并冠心病患者中QT离散度(QTd)的临床意义。方法:观察了肺心病合并冠心病患者中高危组(Ⅰ组)20例和低危组(Ⅱ组)48例及100例正常成人(对照组)的QTd变化。结果:Ⅰ组与Ⅱ组及对照组比较,QTd差异均有显著性(分别为P<0.01)。结论:QTd可作为肺心病合并冠心病室性心律失常或猝死发生的预测指标之一。Objectives： To explore the clinical significanse of QTd in 68 cases with pulmonary heart disease with coronary heart disease. Methods：The changes of QTd were observed in high risk group of 20 cases with pulmonary heart disease with coronary heart disease （ Ⅰ group）, low risk group of 48 cases with pulmonary heart disease with coronary heart disease（ Ⅱ group）and the control group of 100 healthy adults. Results：There were significiant difference among I group, II group and control group（ P 〈 0.01 ）. Conclusions. QTd might be an index for ventricular arrhythmias and heart sudden death in pulmonary heart disease with coronary heart disease.
