  • Title: [Types of left ventricular hypertrophy and their functional changes in essential hypertension].
    Author: Chen X, Wang HY.
    Journal: Zhonghua Xin Xue Guan Bing Za Zhi; 1989 Dec; 17(6):336-7, 382. PubMed ID: 2534657.
    Abstract:
    104 patients of hypertensive left ventricular hypertrophy (LVH) were studied by two-dimensional echocardiography. According to the changes of left ventricular wall thickness, wall mass, end-diastolic volume and ejection fraction, they were divided into three types (concentric, dilated, disproportionate): (1) Concentric LVH 83 cases (79.8%) with thickened ventricular wall and augmented mass. (2) Dilated LVH 13 cases (12.5%) with left ventricular cavity enlarged and both ventricular mass and volume increased, ejection fraction decreased. (3) Disproportionate LVH 8 cases (7.7%), similar to hypertrophic cardiomyopathy with excess increase in interventricular septal thickness. The thickness ratio between interventricular septal and left ventricular posterior wall was greater than or equal to 1.3.
