[Analysis of hemodynamic changes in patients with essential arterial hypertension at rest and during exercise].

Arterial hypertension is a hemodynamic changeable process. The haemodynamic parameters also change when the disease develops. The changes of main haemodynamic parameters according to the intensity of hypertensive disease at rest and during exercise have been presented. The haemodynamic changes observed during short-term physical exercise, may be the indication for evaluation and foreseeing the changes in patients with essential arterial hypertension. Simultaneously the authors draw the attention to a permanent and slow increase in total peripheral resistance (TPR) form the earliest stages of the disease.
