冠心病患者动态心电图检查中P波离散度、T波峰-末间期的变化及诊断价值研究
Changes and diagnostic value of P-wave dispersion and T peak-T end interval in dynamic electrocardiogram in patients with coronary heart disease
摘要
Abstract
Objective:To explore the changes and diagnostic value of P-wave dispersion(Pd)and T peak-T end(Tp-Te)interval in dynamic electrocardiogram in patients with coronary heart disease(CHD).Methods:A total of 203 patients with CHD were enrolled as study group,including 95 cases with myocardial ischemia in myocardial is-chemia group and 108 cases with myocardial ischemia and arrhythmia in arrhythmia group.A total of 90 healthy con-trols during the same period were enrolled as control group.All the objects underwent dynamic electrocardiogram ex-amination to record Pd and Tp-Te interval.Pd and Tp-Te interval were compared between study group and control group,and between myocardial ischemia group and arrhythmia group.The diagnostic value of Pd and Tp-Te interval for CHD and arrhythmia of CHD was analyzed by receiver operating characteristic(ROC)curves.Results:Pd and Tp-Te interval in study group were higher than those in control group(all P＜0.05).AUC of Pd combined with Tp-Te interval in the diagnosis of CHD was greater than that of single index(all P＜0.05).Pd and Tp-Te interval in arrhythmia group were higher than those in myocardial ischemia group(all P＜0.05).AUC of Pd combined with Tp-Te in-terval in the diagnosis of arrhythmia was greater than that of single index(all P＜0.05).Conclusion:The dynamic electro-cardiogram of CHD patients shows an increase in Pd and an extension of Tp-Te interval,and the increase in Pd and an exten-sion of Tp-Te interval are more significant in patients with myocardial ischemia combined with arrhythmia than in patients with myocardial ischemia.The two indexes have high diagnostic value for CHD and arrhythmia of CHD.关键词
