目的 :探讨糖尿病患者的室性心律失常及和 QTd的关系。方法 :对 12 6例糖尿病患者和4 0例正常人的心电图、动态心电图进行分析。结果 :糖尿病患者的 QTd为 62 .9± 17.1ms,室性心率失常的发生率为 4 5.63%。对照组的 QTd为 2 6.1± 14.3ms,室性心率失常的发生率为 2 0 % ,两者有明显差异 ( P<0 .0 1)。结论 :QTd异常的糖尿病患者易发生室性心律失常
Objective: To investigate the relationship between ventricular arrhythmia and QTd in diabetic patients. Methods: The electrocardiogram and ambulatory electrocardiogram of 12 6 diabetic patients and 40 normal people were analyzed. Results: The QTd of diabetic patients was 62.9 ± 17.1 ms, and the incidence of ventricular arrhythmia was 45.63%. The control group had a QTd of 21 6.1 ± 14.3 ms and a ventricular arrhythmia rate of 20%. There was a significant difference between the two (P <0.01). Conclusion: Patients with abnormal QTd diabetes are prone to ventricular arrhythmia
