[Radionuclide ventriculography as a method for assessing the functional status of the heart ventricles in patients with supraventricular tachycardia].
Left and right ventricular function was evaluated by means of radionuclide ventriculography in 44 patients with paroxysms of supraventricular tachycardia without sings of circulatory insufficiency of coronaro- and noncoronarogenic origin. Depending on the efficacy of antiarrhythmic treatment the patients were subdivided in two groups: patients amenable to treatment and patients with refractory arrhythmia. It was established that radionuclide ventriculography allows to objectively evaluate the functional state of both ventricles and to reveal early signs of deterioration of the hemodynamic productivity of the heart in patients with paroxysms of supraventricular tachycardia. Reduction of the pumping function of the right ventricle in patients with refractory tachycardia along with hyperkinesia of its separate segments, changes of left ventricular rate and an increase of the terminal diastolic and systolic volumes of both ventricles without changes of the stroke volume may be a criterion of refractoriness of arrhythmia in this category of patients.
