A maioria dos pacientes (ptes) com bradiarritmias sintomáticas que requerem o implante de (MP) definitivos são idosos. Consequentemente, os adultos jovens, faixa etária entre 20 e 40 anos, estão poucos representados nos estudoas de resultados após o implante de MP. O objetivo do presente estudo foi ...
We report the case of a 69 year-old male who developed congestive heart failure functional class IV (NYHA). The admission electrocardiogram (EKG) revealed sinus rhythm, PR interval of 240 ms, QRS interval of 110 ms, the QRS vector of 0 degree, Q waves from V1 to V6, tall R waves from V1 to V4 that decrea...
PURPOSE: To evaluate the sensitivity and specificity of myocardial perfusion scintigraphy in the detection of coronary artery disease in patients with right bundle branch block (RBBB). METHODS: Thirty one patients (24 male, 62.3 +/- 10.5 years) with RBBB, submitted to myocardial perfusion scintigraphy as...

PURPOSE: To compare the correlation between the departure areas (DA), negative or positive, in patients whose electrocardiogram showed left bundle branch block (LBBB) and association with left ventricular hipertrophy (LVH) and myocardial infarction (MI), to the electrocardiographic (ECG) and vectocardiog...
A 43 year old man was admitted to the hospital due to a syncopal episode and presented on the electrocardiogram a pattern of right bundle branch block (RBBB) associated with ST segment elevation from V1 to V4 and normal QT interval. Acute myocardial infarction was suspected but was not confirmed by labor...
PURPOSE: To evaluate septal perfusion and contractility in patients with left bundle branch block (LBBB). METHODS: Twenty patients were submitted to myocardial scintigraphy with Tecnecium-99m isontrile after exercise and dipyridamole infusion. The septal contractility was observed during the radionuclide...
PURPOSE--To determine the type of cardiac disease causing left bundle branch block (LBBB) in Porto Alegre, Brazil, and to assess the role of associated left axis deviation (-30 degrees or more in the frontal plane) in order to identify a specific etiology of LBBB. METHODS--Through reports from the assist...
PURPOSE--To evaluate possible morphological changes in chronic chagasic of the right bundle trabecular branch (RB) with right branch block (RBB) and to draw clinicopathological correlations. METHODS--Eight RBB chronic chagasic septo-marginal trabeculae (SMT) (group A), six left branch block (LBB) chagasi...
