Objective To compare the QT interval ,QTc, Tp-e interval and Tp-e/QT ratio between patients with type 2 diabetes and normal individuals.Methods one hundred patients with diabetes were randomly selected, and one hundred age-and-gender-matched normal healthy individuals were selected as controls.The QT interval ,R-R interval, Tp-e interval were measured respectively on electrocardiogram precordial lead V2,and the QTc and Tp-e/QT ratio were calculated.Results The QT interval was no significant difference between diabetic group and control group(P>0.05); however, the QTc in the diabetic group was higher than that of control group(P<0.05);moreover, the Tp-e interval and Tp-e/QT ratio in diabetic group was higher than those in the control group(P<0.01).Conclusion QTc, Tp-e interval and Tp-e/QT ratio increase in type 2 diabetes, which may be a useful electrocardiographic index of arrhythmogenesis.

心肌病为一组临床表现多种多样,具有结构异常和(或)电异常,由各种原因通常是遗传原因造成,常表现为心室异常肥厚或扩张,但也可以正常.原发性心肌病指仅限于心肌或主要累及心肌的疾病,继发性心肌病指心肌病变是全身性疾病的一部分.中华医学会心血管病分会于将原发性心肌病分类和命名为扩张型心肌病(DCM)、肥厚型心肌病(HCM)、致心律失常性右室心肌病(ARVC)、限制型心肌病(RCM)和未定型心肌病五类.本文
