[Changes in basic hemodynamic and electrocardiographic parameters in patients with severe vasorenal hypertension].

Major hemodynamic and electrocardiographic parameters were examined in 47 patients with severe vasorenal hypertension at rest, and in 20 patients after stress exposure. Three (hyper-, eu- and hypokinetic) types of circulation were demonstrated, like the ones seen in essential hypertension. Hemodynamic values at rest were indicative of relative cardiovascular compensation in severe vasorenal hypertension. Stress testing demonstrated that exercise disrupted that compensation. Arterial blood pressure response to physical stress showed no correlation to baseline values of the parameters examined.
