[Efficacy of the electrocardiographic diagnosis of left ventricular hypertrophy on the basis of gender].
OBJECTIVE
To determine the efficacy of electrocardiographic criteria of Left Ventricular Hypertrophy (RVL greater than 11 mm, SVE3 + RVL greater than 20 mm in females and greater than 28 mm in males, SV1 + RV6 or SV2 + RV5) in hypertensive patients according to sex.


METHODS
Retrospective study. Gold standard M mode echocardiography.


METHODS
Pulido Valente Hospital Department of Cardiology (Lisbon).


METHODS
56 hypertensive patients (age 55.1 s.d. 11.6), 27 females and 29 males, with LVH by echocardiographic Left Ventricular Mass Index (LVMI) greater than 110 g/m2 in woman and greater than 134 g/m2 in men, respectively 10 and 19 patients. The LVMI was calculated by the formula of the American Society of Echocardiography modified by Devereux.


RESULTS
The LVMI was smaller in females than in males (P = 0.007). The Cornell Criteria had the greatest efficacy in woman and the Sokolow criteria satisfactory efficacy but in man. The electrocardiogram (1 of the 4 criteria positive) had low diagnostic efficacy in woman.


CONCLUSIONS
We concluded that echocardiogram is the best non-invasive diagnostic tool of Left Ventricular Hypertrophy in hypertensive females and is necessary to adjust and choose the electrocardiographic Left Ventricular Hypertrophy criteria according to sex.
