摘　　要：目的:分析心电图检查中T波峰-末间期(Tp-Te间期)及Tp-Te间期离散度对扩张型心肌病患者的预后评估效果。方法:将接受心电图检查的70例扩张型心肌病患者以是否发生恶性心律失常分为观察组、对照组,比较心电图指标及超声指标,并分析两者间的相关性。结果:观察组Tp-Te间期、离散度及左室舒张末期内径(LVEDD)均高于对照组,左室射血分数(LVEF)、左室室间隔厚度(IVST)则低于对照组(P<0.05)。Tp-Te间期、Tp-Te间期离散度与LVEF、IVST呈负相关,与LVEDD正相关。结论:Tp-Te间期、Tp-Te间期离散度能较好地反映扩张型心肌病患者心功能情况及恶性心律失常风险。Objective:To analyze the effect of Tp-Te interval and Tp-Te interval dispersion on prognosis of patients with dilated cardiomyopathy.Methods:70 patients with dilated cardiomyopathy were divided into observation group and control group according to whether malignant arrhythmia occurred.ECG and ultrasound indexes were compared and the correlation between them was analyzed.Results:Tp-Te interval,dispersion and left ventricular end-diastolic diameter(LVEDD)in observation group were higher than those in control group,while left ventricular ejection fraction(LVEF)and left ventricular septal thickness(IVST)in observation group were lower than those in control group(P<0.05).The dispersion of Tp-Te interphase and Tp-Te interphase was negatively correlated with LVEF and IVST,and positively correlated with LVEDD.Conclusion:Tp-Te interval and Tp-Te interval dispersion can reflect the cardiac function and the risk of malignant arrhythmia in patients with confluent heart disease.
