[Concentric left ventricular hypertrophy in patients with hypertension. When should ventricular hyperexcitability be searched for?].
The main objective is to determine when concentric left ventricular hypertrophy (LVH) increased ventricular ectopic activity in essential hypertension. Twenty-four hours Holter monitoring was recorded in 56 patients with essential hypertension: 20 without LVH and 36 with concentric LVH determined by echocardiography (left ventricular mass greater than 215 g). According the degree of septal thickness (ST), patients were classed in 4 groups: (formula; see text) This study allows to conclude that mean and severe concentric LVH (ST greater than or equal to 12) detected by echo are associated with a greater PVC and a higher Lown's class ventricular ectopy. The degree of ST was strong correlated with the Lown's classification (r = 0.6, p less than .0001).
