[Prevalence and diagnostic evaluation of electrocardiographic signs of left ventricular hypertrophy in arterial hypertension in a population study].
Signs of left ventricular hypertrophy according to Minnesota code (categories 3-1, 3-3) and ECG findings (RAVL greater than or equal to 7 mm, RV5,6 + SV2 greater than 35 mm, RV6 greater than RV4, with RV6 greater than RV5; S V2 greater than 24 mm and RI + SIII greater than 25 mm) were studied in 779 men, aged 40-54 and 296 women, aged 35-50 in whom essential hypertension was revealed during screening. The control group was formed of a random sample from 341 normotensive men and 103 women of the same age. Signs of left ventricular hypertrophy were observed in 18.2% of men and 5% of women in patients with essential hypertension and in 6.7% of men and 5.8% of women in the control group. Electrocardiographic findings of left ventricular hypertrophy are of high specificity (more than 0.9) and low sensitivity (about 0.1) in regard to essential hypertension.
