title: [Effect of nitrates on cardiodynamics in patients with atrioventricular block treated by electrocardiostimulation].
abstract: The clinical and hemodynamic effect of nitrates with both their single administration and a prolonged therapy in patients with atrioventricular block related to elecrocardiostimulation has been studied. Nitroglycerin has been found to exercise its action in two phases: first decreasing and then increasing cardiac output. The character of phase I has been ascertained to correlate with the potential development of various complications during the treatment with nitrates. A conclusion has been drawn as to the efficacy of nitrosorbid employment in the multiple modality treatment of chronic cardiac insufficiency in patients with an implanted cardiostimulator.
