[The effect of an acute pharmacologic test with prozerin on cardiac and central hemodynamic indices in patients with myasthenia].

It has been shown that the overwhelming majority of myasthenia patients manifest changes in the cardiovascular system characterized by cardiac pains of different nature, duration and intensity, by electrocardiographic changes and lowering of the central hemodynamics and myocardial contractility. A direct relationship was established between heart involvement into the pathological process and myasthenia gravity as well as the underlying disease standing. The changes in cardiovascular function were not affected by the acute use of neostigmine.
