摘要：Objective: To evaluate the changes in Tp-e interval (an interval from the peak to the end of the T wave),QT interval and Tp-e/QT ratio of the body surface ECG in patients with left ventricular hypertrophy (LVH).Methods: The Tp-e interval and QT interval were measured on body surface ECGs in 42 patients without either hypertension or LVH (control group),41 patients having hypertension but not LVH (non-LVH group),and 38 patients with both hypertension and LVH (LVH group). Results: The mean corrected QT (QTc) interval,and mean corrected Tp-e[T(p-e)c]interval were significantly longer in the LVH group (0.430±0.021s vs.0.409±0.019s,p<0.01; 0.098±0.013s vs. 0.088±0.01 1s,respectively) than those in the control group. The Tp-e/QT ratio was also amplified in LVH group (0.232±0.028 vs.0.218±0.027) (p<0.05). Conclusion: LVH increased the QT interval,Tp-e interval and Tp-e/QT ratio of the body surface ECG.
