[False positive results of exercise tests with thallium myocardial scintigraphy].
The authors have examined supposed causes of positive Th-201 stress scintigraphy. Patients were divided into two groups according to the presence of exercise-induced transitory hypoperfusion or in absence of it. In both groups negative coronarograms were verified. Results of two groups were compared according to parameters of the left ventricle function, pulmonary pressure, to the presence of disorder of system stimulus-conduction (LBBB, RBBB), mitral prolapsus, foramen ovale apertum, anomalous coronary anatomy, level of load during exercise, body weight, heart volume-index. Significant difference was found in disorder of left ventricle motion, ejection fraction and in comprehensive value of left ventricle function (F1).
