Popis: To evaluate septal perfusion and contractility in patients with left bundle branch block (LBBB).Twenty patients were submitted to myocardial scintigraphy with Tecnecium-99m isontrile after exercise and dipyridamole infusion. The septal contractility was observed during the radionuclide ventriculography. All patients were submitted to coronariography.Twenty patients were studied and 17 (85%) had a normal left anterior descending (LAD) artery. Nine (53%) patients had abnormalities in septal perfusion after the exercise and 2 (12%) after dipyridamole infusion. All patients had abnormalities in septal contractility during the radionuclide ventriculography.The myocardial scintigraphy after dipyridamole infusion showed better specificity in the diagnosis of a LAD lesion. The radionuclide ventriculography was an efficient method to evaluate the septal contraction abnormalities in patients with LBBB.
