【摘要】 目的 探讨慢性肺源性心脏病(PHD)心电图QT离散度(QTd)及JT离散度(JTd)与心功能不全(CDF)的关系。方法 PHD病人82例,按病情分为心功能Ⅱ级20例,Ⅲ级34例,Ⅳ级28例。测量常规12导联心电图QT及JT,并与对照组60例进行比较。结果 CDF各级QTd、JTd分别为心功能Ⅱ级(52.9±12.7)ms,(51.6±12.2)ms;心功能Ⅲ级(66.1±12.8)ms,(65.3±12.4)ms;心功能Ⅳ级(88.9±16.5)ms,(88.2±15.8)ms;对照组为(36.1±9.2)ms,(35.4±9.6)ms,各组与对照组、各组之间比较差异有非常显著性(P<0.01)。结论 慢性肺源性心脏病CDF早期,心电图QTd、JTd显著增加,可作为肺源性心脏病早期诊断依据之一,QT越大,病情越重,预后越差,动态观察可判断病情,提示预后。

【Abstract】 Objective To detect relationship between dispersion of QT(QTd)and JT dispersion(JTd)and cardiac insufficiency in chronic pulmonary heart disease(PHD).Methods 82cases with PHD were divided into3groups according to the degree of cardiac insufficiency:classⅠ(n=20),classⅡ(n=34),classⅢ(n=28).The rouˉtine12leads ECG was mesured and compared with control group.Results QTd and JTd was(52.9±12.7)ms and(51.6±12.2)ms(classⅠ),(66.1±12.8)ms and(65.3±12.4)ms(classⅡ),(88.9±16.5)ms and88.2±15.8ms(classⅢ),(36.1±9.2)ms and(35.4±9.6)ms(control group)respectively.The difference among three groups and to control group was significant(P<0.01).Conclusion The increase of QTd and JTd in ECG is one of di……
