Conventional ECG still plays an important role in the overall knowledge of Chagas' cardiopathy, because of its importance in longitudinal and epidemiological studies, its diagnostic value, and its utility in prognostic evaluation. The authors discuss these aspects, as well as the use of ECG in the acute ...
The aim of the study was to register the prevalence of late potentials (LP) in patients with chronic Chagas' heart disease (CCD) and the relationship with sustained ventricular tachycardia (SVT). 192 patients (96 males), mean age 42.9 years, with CCD were studied through a Signal Averaged ECG using time ...
PURPOSE--To present initial experience on radiofrequency (RF) ablation of atrial flutter (AFL) guided by anatomic and electrophysiologic parameters. METHODS--Eight patients (six males), mean-age of 42 +/- 17.5 years with chronic type I AFL (mean cycle length of 251 +/- 14.3 msec, range 240 to 280 msec) w...
PURPOSE--To study by using the signal-averaged P wave, the atrial activation of patients with documented episodes of paroxysmal atrial fibrillation (PAF). METHODS--This study enrolled a total of 20 patients with documented episodes of paroxysmal atrial fibrillation (males 14; mean age 58.4 +/- 10.6 years...
The lack of facilities sometime blocks the use of thrombolytic therapy in public hospitals. In this report, initial experience with the use of thrombolytics in a Municipal Hospital located in São Paulo suburb area, which has no hemodynamic laboratory available, is reported. Prospectively, 45 patients ad...
Six days old neonate with pulmonary atresia and intact ventricular septum is reported in which a communication was established between the right ventricle and the pulmonary artery. The membraneous atresia was perforated with a special radiofrequency catheter 2F connected to a Hat 200S radiofrequency gene...
PURPOSE--To determine the benefits of noninvasive tests in the characterization of heart disease in children referred due to heart murmur. METHODS--Two hundred and thirty three consecutive children were fully examined with the aid of the electrocardiograma (ECG), chest X-ray and echocardiogram (ECHO). Th...
A 22 months old infant with agenesis of right pulmonary artery, without other associated congenital heart defects, is reported. Reconstruction of pulmonary arteries by connecting them through a 7mm Goretex tube was performed, with clear clinical improvement in view of disappearance of signs of cardiac in...
