Abstract：ObjectiveTo discuss the quantitative expression of the changes of ECG Sokolow index (Rv5+Sv1) and Tv5/R with left ventricular hypertrophy(LVH). MethodsRetrospectively analyze ECG baseline and its changes after one year, and record the changes of ECG voltage as well as left ventricular mass index (LVMI) of 80 patients with hypertension.With the help of multiple linear regression analysis, the correlation between the changes of ECG Sokolow index and Tv5/R with those of LVMI was analyzed.Results For patients with hypertension, the changes of LVMI showed a significant linear correlation with the changes of ECG Sokolow index and Tv5/R. An empirical formula was derived which was based on statistical data. ConclusionThe changes of ECG Sokolow index and Tv5/R predict the corresponding changes of LVMI. It therefore offers a method economical and convenient enough to be applied in the postoperative followup of patients with LVH and the guidance of clinical treatment.
