Abstract 【Objective】To explore the diagnostic efficacy of different electrocardiographic criteria for hypertensive patients with left ventricular hypertrophy. 【Methods】The clinical data of 180 patients with hypertension admitted to our hospital from May 2019 to May 2022 were retrospectively analyzed. All patients underwent echocardiography and electrocardiography, and the diagnosis of echocardiography was regarded as the gold standard. Kappa test was used to analyze the sensitivity, specificity, accuracy and consistency of Sokolow-Lyon voltage standard, Cornell voltage standard, Peguero-Lo Presti voltage standard and the combination of three ECG voltage standards in the diagnosis of left ventricular hypertrophy. 【Results】 Echocardiography was performed in 180 patients with hypertension. The results showed that 102 patients(56.67%) had left ventricular hypertrophy and 78 patients(43.33%) had non left ventricular hypertrophy. The consistency analysis showed that the sensitivity of Sokolow-Lyon voltage standard for the diagnosis of left ventricular hypertrophy was 0.373, the specificity was 0.821, and the accuracy was 0.567(Kappa=0.180,P=0.414); The sensitivity, specificity and accuracy of Cornell voltage standard in the diagnosis of left ventricular hypertrophy were 0.490, 0.872 and 0.656(Kappa=0.340,P=0.207); The sensitivity, specificity and accuracy of Peguero-Lo Presti voltage standard in the diagnosis of left ventricular hypertrophy were 0.863, 0.744 and 0.811(Kappa=0.612, P<0.001); The sensitivity, specificity and accuracy of three electrocardiographic voltage criteria in the diagnosis of left ventricular hypertrophy were 0.922, 0.923 and 0.922 respectively(Kappa=0.842, P<0.001). 【Conclusion】 The sensitivity, accuracy and kappa value of Peguero-Lo Presti voltage standard in the diagnosis of left ventricular hypertrophy are better than Sokolow-Lyon voltage standard and Cornell voltage standard. The combination of three ECG voltage standards can improve the sensitivity, specificity and accuracy in the diagnosis of left ventricular hypertrophy.
