[Diastolic relaxation and left ventricular blood filling in patients with hypertension].

Disorders of left-ventricular diastolic relaxation and blood filling in patients with first- and second-stage essential hypertension are shown, by means of echo-, radio- and apexcardiography, to be due to the effects of arterial blood pressure, hemodynamic changes, heart rate and the magnitude of left-ventricular hypertrophy. Antihypertensive treatment, affecting major parameters of disease, brings about the recovery of the heart's diastolic function.
