中等强度运动对糖尿病合并冠心病患者QT离散度的影响

Influence of moderate intensity exercise on QTd of patients with both CHD and T2DM

目的:观察运动疗法对冠心病合并糖尿病患者的QT间期离散度的影响。方法:用同步12导联心电图测定80名糖尿病合并冠心病患者规律运动30 d、60 d、90 d后QT离散度。结果:受检者运动60 d后和运动90 d后QT离散度均下降,差异有统计学意义(P<0.05)。结论:中等强度运动60 d和90 d后,糖尿病合并冠心病患者的QT离散度下降。

Objective： To study the change of QT dispersion （QTd） of patients with both coronary heart disease （CHD） and type 2 diabetes mellitus （T2DM） in exercise training. Methods： All patients（ n = 80） were recruited in our study. QTd were recorded by 12- lead ECG. The QTd of the patients before exercise,30,60 and 90 days after exercise were recorded. Results：QTd of 60 days after exercise and 90 days after exercise decreased significantly in comparison with that before exercise （ P 〈 0.05 ）. Conclusion： After 60 and 90 daystmoderate intensity exercise, QTd of patients with both CHD and T2DM may decrease.
