[Use of phase images in radionuclide ventriculography for topical diagnosis of Wolff-Parkinson-White syndrome and sources of pathologic rhythm of the heart ventricles].

The paper presents the results of the mapping of various types of the Wolff-Parkinson-White syndrome and ventricular arrhythmias by using phase images of radionuclide ventriculograms as compared to 12 leads and electrophysiological studies. Phase images are a highly informative method that supplements an electrophysiological study in the topical diagnosis of abnormal tracts and ventricular arrhythmias.
