[Studies of heart function using apex cardiography in pregnancy-induced hypertension before and following therapy with dihydralazine sulfate].
The apex cardiogram and its 1st differential quotient were simultaneously registered with the phonocardiogram, the electrocardiogram and the curve of the carotid pulse in 10 female patients with pregnancy-induced hypertension before and after the therapy with dihydralazine sulphate. 10 healthy pregnant women of the same trimenon served as comparative group. Altogether 20 parameters were investigated which are regarded as acknowledged indices of the compliance, the contractility and the ability of relaxation. The changes which we found point to an increase of the preload in H-gestosis, which seems to be regressive after the therapy with dihydralazine sulphate. The parameters of contractility and relaxation, including the systolic time intervals, remained uninfluenced.
