Abstract

Although many patients with hypertension develop isolated septal hypertrophy (ISH) rather than concentric or eccentric left ventricular (LV) hypertrophy, limited data are available on cap diac structure, function, and arrhythmias in hypertensive patients with ISH. Clinical features, hemodynamics, M-mode echocardiograms, and 24-hour electrocardiographic recordings were evaluated in 21 healthy normotensive subjects, 23 hypertensive patients without LV hypertrophy, 31 hypertensive patients with concentric LV hypertrophy, and 23 hypertensive patients with ISH to determine the prevalence and complexity of cardiac arrhythmias and diastolic LV filling abnormalities. Age, sex, race, obesity indexes, preload, ejection fraction, and LV contractility were similar in all4 groups, and arterial pressure and afterload were statistically similar in the 3 hypertensive groups. Left atrial emptying index (p <0.01)and peak LV filling rate (p <0.01), 2 indexes of diastolic LV filling, were significantly reduced in the 3 hypertensive groups compared with the normotensive group. The duration of rapid LV filling, however, was significantly prolonged only in hypertensive patients with concentric LV hypertrophy and ISH (p <0.05) but not in hypertensive patients without LV hypertrophy. The prevalence (p <0.001) and complexity (p <0.001) of ventricular ectopic activity was also significantly increased to a similar degree in hypertensive patients with concentric LV hypertrophy and in those with ISH compared with normotensive subjects or hypertensive patients without LV hypertrophy. The prevalence and complexity of atrial ectopic activity was only increased significantly (p <0.001) in those with ISH.
