Abstract: | A total of 120 patients with essential hypertension, stage I and II, were examined, using radio- and electrocardiography, before and after a hypotensive treatment. Two mechanisms: excessive volume (in patients with hyperkinetic circulation) and excessive pressure (in those with normo- and hypokinetic circulation) were found to form the basis of the formation of left-ventricular muscular hypertrophy. Antihypertensive effect of treatment reducing electrocardiographic signs of left-ventricular muscular hypertrophy was shown to be related to improved arterial pressure control and lesser adrenergic influence on the heart. |
