Abstract Objective To compare the clinical value of different voltage criteria of 12-lead routine ECG in diagnosing left ventricular hypertrophy (LVH) related to primary hypertension, and to explore a method for improving the diagnostic efficiency of ECG. Methods A total of 161 patients with primary hypertension admitted to our hospital were selected. They all underwent examinations of echocardiography and 12-lead routine ECG, and these results were comparatively analyzed. According to the left ventricular mass index (LVMI), these patients were divided into LVH positive group (67 cases) and LVH negative group (94 cases). The sensitivity, specificity and Youden index of Sokolow, Cornell and Peguero-Lo Presti criteria, and the combined regimen were calculated based on ECG data, and compared between the genders. Results The values of left ventricular mass and LVMI in the LVH positive group are significantly higher than those in the LVH negative group with statistically significant differences (P<0.01). The sensitivity of Peguero-Lo Presti criterion is higher than that of the other two criteria, but the specificity is lower. Compared with single diagnostic criterion, the sensitivity of the combined regimen is the highest while its specificity is the lowest. Either in male or female patients, the Youden index of the combined regimen is the highest, followed by the index of Peguero-Lo Presti criterion, and the other two criteria. Conclusion Peguero-Lo Presti criterion is more recommended in diagnosing LVH with single diagnostic criterion. The combined regimen of the three criteria helps to increase the detection rate of LVH by ECG, which provides certain clinical application value.
