title: [Myocardial functional state in neurocirculatory dystonia].
abstract: The function of the myocardium during bicycle ergometry (submaximum exertion) was studied in 97 patients with neurocirculatory dystonia (NCD) bymeans of polycardiography. Three types of reaction of cardiodynamics to the exertion were revealed: a favourable reaction, similar on the whole to the normal reaction; hyperdynamic reaction which was evidence of hyperkinetic cardiac activity; unfavourable reaction associated with impaired myocardial contractility. Clinical and instrumental comparison enabled the author to detect some regular features as the result of which the severity of NCD could he objectified, the decrease in physical exertion tolerance to be assessed differentially, and the working capacity in persons with the pathological condition to be assessed.
