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.

Abstract

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.
