[The physical work capacity of patients with neurocirculatory dystonia and the early ventricular repolarization syndrome].
A total of 35 patients with neurocirculatory dystonia (NCD) presenting with a syndrome of early repolarization of ventricles (SERV), who comprised the principal group, were studied for an effect of the syndrome under conditions of the bicycle ergometer [correction of veloergometer] exercise test on EKG as well as on the indices for physical performance. The results obtained were compared to those in 32 NCD cases without SERV signs (control group) and 20 essentially healthy subjects. NCD SERV cases, while in bicycle ergometry [correction of veloergometry], developed depression up to the isometric line of the elevated St-segment, and in a portion of cases it was 0.5--1 mm under the isoline with subsequent restoration of EKG findings to the baseline level after the cessation of the test. SERV occurrence in NCD patients did not influence exercise tolerance, increments of heart rate, arterial blood pressure and indices for "double product" under bicycle ergometric [correction of veloergometric] testing. Pattern of changes in the above indices depended, for the most part, on the condition of the baseline vegetative tone.
