[Phase structure of cardiac activity and the function of renal vessels in nephrogenic hypertension]

A total of 25 patients with renal affections, in whom an elevated arterial pressure had been ascertained clinically, were examined for the phasic structure of the cardiac action and for the functional state of the renal vessels by employing rheography. Of these patients 8 had urolithiasis, 6-tuberculosis, 7-polycystosis and 4-renal tumours. Their systolic pressure averaged 160-220 mm and diastolic-80-110 mm. In patients with nephrogenic hypertension the tone of systemic vessels and the peripheral resistance are shown to go up. The changes are accompanied by a phasic syndrome of a high diastolic pressure. A complex investigation into the phasic structure of the cardiac activity and the functional condition of the renal vessels by employing rheography makes it possible to disclose the sequential lesion of the vessels in patients suffering from nephrogenic hypertension.
