[Diagnostic value of electrocardiographic criteria of left ventricular hypertrophy in hypertension in a population study].

The correlation between the diagnosis by the criteria of the Minnesota code and the known indices of left ventricular hypertrophy (LVH) (RAVL greater than or equal to 7 mm, Rv5,6 + Sv1,2 greater than greater than 35 mm, Rv6 greater than Rv4 Sv2 greater than 24 mm) in 12 standard leads and the roentgenocardiometric data has been analyzed. 156 males (35-54 years of age) and 175 females (30-52 years of age) suffering from first and second stage of essential hypertension as well as 60 male and 30 female controls from the staff population of the Likhachev Plant have been studied. The study has shown that sensitivity of the above ECG criteria for LVH, diagnosed by roentgenocardiometry, is higher in males than in females, their specificity being higher in females. The correlation ratio of ECG criteria with established LVH is 0.18 for males, and 0.26 for females. In the first stage of essential hypertension no correlation between ECG criteria for LVH and roentgenocardiometric data were observed. The second stage of essential hypertension was characterized by negative correlation between ECG criteria for LVH and roentgenocardiometric data.
