[Contribution of electrovectorcardiography in the diagnosis of hypertrophic cardiomyopathy. Comparative study with an echocardiographic score].
The object of the study was to define spreading and quantitative criteria of left ventricular hypertrophy in echocardiography by using a "score"--for this, the left ventricle has been divided into 11 regions and a "score" attributed to each one of them--and to find the correlation with the vectocardiogram (VCG) in 42 patients with hypertrophic myocardiopathy (HM). The results obtained show the following: 1) the left ventricular hypertrophy aspect on the ECG and the VCG is very sensitive for the identification of a diffuse HM; 2) the necrosis, hemiblock or septal hypertrophy indicate a hypertrophy located in the forepart septum or the whole of the septum; 3) the giant T waves indicate a hypertrophy of the apex; 4) a left ventricular hypertrophy associated with a necrosis or a hemiblock indicate a global myocardiopathy, with the basal region of the septum largely affected.
