[Functional state of the heart in ventricular tachycardia as evidenced by radionuclide ventriculography]

The paper presents the results of examining the structural and functional parameters of the ventricles in 40 patients with ventricular tachycardia by radionuclide ventriculography on the first passage of a radioactivity bolus. Twenty patients had ventricular tachycardia resistant to antiarrhythmic agents. The patients with ventricular tachycardia were found to have systolic and diastolic dysfunction of the both ventricles. Lower pump function and higher volumetric parameters of the left ventricle in patients with refractory ventricular tachycardia concurrent with hyperkinesia of some right ventricular segments and abnormal velocity and time variables can be a criterion for resistance to antiarrhythmic agents in this group of patients.
