1. Cardiopulmonary Exercise Testing in Patients with Implantable Cardioverter-Defibrillator: A Retrospective Study
Abstract Background: Cardiopulmonary exercise testing is widely used in the evaluation of patients with left ventricular dysfunction, and some of these patients have an implantable cardioverter-defibrillator (ICD). However, this test presents specific challenges because of the susceptibility to ventricular arrhythmias during maximal levels of exercise. Obj

2. Isolated Non-Compacted Myocardium: Should We Consider the Presence of Extrasystoles as the Initial Manifestation?
Abstract Ventricular non-compaction occurs due to failure in myocardial morphogenesis during the fetal period. Patients can have heart failure, as well as systemic complications due to thromboembolism and cardiac arrhythmias. Early diagnosis is essential. We present the case of an asymptomatic 49-year-old woman who initially manifested ventricular extrasysto

3. Subclinical Thyroid Dysfunction was not Associated with Cardiac Arrhythmias in a Cross-Sectional Analysis of the ELSA-Brasil Study
Resumo Fundamento: A associação de disfunção tireoidiana subclínica (DST) com arritmias cardíacas permanece controversa, particularmente na população não idosa. Objetivo: Investigar se a DST está associada a arritmias cardíacas em uma coorte de adultos de meia-idade e idosos. Métodos: Dados da linha de base do Estudo Longitudinal de Saúde do

5. Morbidity of Chagas heart disease in the microregion of Rio Negro, Amazonian Brazil: a case-control study
A case-control study on the morbidity of Chagas heart disease was carried out in the municipality of Barcelos in the microregion of the Rio Negro, state of Amazonas. One hundred and six individuals, who were serologically positive for Trypanosoma cruzi infection, as confirmed by at least two techniques with different principles, were matched according to age

6. Redução da densidade de extrassístoles e dos sintomas relacionados após administração de magnésio por via oral / Successful improvement of frequency and symptoms of premature complexes after oral Magnesium administration
Introdução: As extrassístoles ventriculares e supraventriculares (EV e ESSV) são frequentes e muitas vezes sintomáticas. O íon magnésio (Mg) desempenha um papel importante na fisiologia do potencial de ação transmembrana celular e do ritmo cardíaco. Objetivo: Avaliar se a administração do Pidolato de Magnésio (PMg) em pacientes com EV e ESSV é

7. Resultado do tratamento cirurgico da fibrilacao atrial cronica / Results of the surgical treatment of chronic atrial fibrillation
Objective – Report clinical experience in surgical treatment of atrial fibrillation (AF) by Cox-maze procedure. Methods – 61 patients underwent surgical treatment for AF. Two had primary AF and 59 AF secondary to heart disease (2 atrial septal defects, 57 mitral). Ages ranged from 20 to 74 years (mean = 49). There were 44 females (72%). The surgical tech

8. Correlação entre função ventricular direita e capacidade funcional em pacientes com cardiopatia chagásica crônica
Chronic Chagas heart disease constitutes the most severe manifestation of Chagas disease, with great heterogeneity in its clinical presentation. The degree of myocardial dysfunction is a prognostic factor, but with no direct relation with the functional class. The present study evaluated the correlation between functional capacity and right ventricular funct

9. Maternal-fetal monitoring of patients with rheumatic heart disease during dental procedure under local anesthesia / Monitorização materno-fetal da portadora de doença valvar reumática durante procedimento odontológico sob anestesia local
During pregnancy, the organic systems of a woman are subjected to physiological modifications consequential to hormonal, anatomic and metabolical alterations. The most significant modification in the circulatory system is an increased cardiac output from the first three months of gestation. Women with heart disease may present with severe complications durin

10. Electrocardiographic findings in Mexican chagasic subjects living in high and low endemic regions of Trypanosoma cruzi infection
In México the first human chronic chagasic case was recognized in 1940. In spite of an increasing number of cases detected since that time, Chagas disease in México has been poorly documented. In the present work we studied 617 volunteers subjects living in high and low endemic regions of Trypanosoma cruzi infection with seroprevalence of 22% and 4% respec

11. Surgical myocardial revascularization without extracorporeal circulation
OBJECTIVE: To assess the immediate postoperative period of patients undergoing myocardial revascularization without extracorporeal circulation with different types of grafts. METHODS: One hundred and twelve patients, 89 (79.5%) of whom were males, were revascularized without extracorporeal circulation. Their ages ranged from 39 to 85 years. The criteria for

12. Supression of ventricular extrasystoles by perhexiline.
The antiarrhythmic effects of perhexiline were investigated in 13 of 20 patients with frequent and long standing ventricular extrasystoles in a double blind crossover trial using 24-hour electrocardiograph tape recordings, routine electrocardiograms, and treadmill exercise testing. With a dose of 300 to 400 mg per day, there was a significant decrease (mean
