Abstract
Objective To analyze the clinical value of 12-leads electrocardiogram in the differential diagnosis of patients with hypertrophic cardiomyopathy and hypertensive left ventricular hypertrophy. Methods 48 patients with hypertrophic cardiomyopathy was taken was group A and 50 patients with hypertensive left ventricular hypertrophy was taken was group B in our hospital during January 2017 and June 2018. All the patients were detected by 12-leads electrocardiogram, the electrocardiogram indexes (Tp-e interval indicator, electrocardiogram dispersion degree, occurrence of abnormal Q wave, inverted T wave, and ST-segment depression) were compared between the two groups. The diagnostic value of 12-leads electrocardiogram on hypertrophic cardiomyopathy was analyzed. Results The Tp-e interval of Ⅱ , aVR, aVF, V6 leads of group A were significantly greater than those of group B (P<0.05); the QTmax, QTmin, QTd of group A were significantly greater than those of group B (P<0.05). The occurrence rate of abnormal Q wave was 39.58％ (19/48) in group A, and 14.00％ (7/50) in group B, with statistically significant difference between the two groups (P<0.05). The sensitivity and specificity of Ⅱ lead Tp-e interval ≥64 ms, V6 lead Tp-e interval ≥69 ms, and abnormal Q wave on hypertrophic cardiomyopathy was 77.83％, 77.42％, 70.44％, 81.69％, 74.50％, 95.42％. Conclusion The 12-leads electrocardiogram could be used to identify patients with hypertrophic cardiomyopathy and hypertensive left ventricle hypertrophy, Ⅱ lead Tp-e interval ≥64 ms, V6 lead Tp-e interval ≥69 ms, and abnormal Q wave have high diagnostic value on hypertrophic cardiomyopathy.关键词
