OBJETIVO - Avaliar a medida da dispersäo do QT (DQT) em portadores de hipertensäo arterial sistêmica, com e sem hipertrofia ventricular esquerda (HVE) e comparar com indivíduos normais. MÉTODOS - Foram submetidos a ecocardiograma e eletrocardiograma (ECG) de 12 derivaçöes simultâneas, alinhadas, ...
PURPOSE: To evaluate the "normal" or low-voltage P wave of the 12-leads conventional electrocardiogram (ECG), in patients with serious electric ventricular disturbances in hypertrophic (HC) and dilated (DC) cardiomyopathies. METHODS: Twenty cases of cardiomyopathies, 11 HC and 9 DC, ages ranging from 23 ...
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 examine heart disease in the systemic lupus erythematosus (SLE) and the association of cardiac abnormalities with anticardiolipin antibodies (ACL). METHODS: Sixteen patients with active SLE disease (group I) were compared with 14 patients without disease activity (group II). A control group o...
