La repolarización auricular y sus implicaciones clínicas

Rev. colomb. cardiol; 27 (1), 2020
Resumen La onda P en el electrocardiograma representa exclusivamente la despolarización de las aurículas puesto que la repolarización auricular queda oculta en el QRS. Sin embargo, cuando la repolarizacón auricular se hace evidente en el electrocardiograma se convierte en un elemento clave para el di...

Evaluation of Electrocardiographic Ventricular Depolarization and Repolarization Variables in Type 1 Diabetes Mellitus

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: The risk of cardiovascular events and sudden death increases with type 1 diabetes mellitus (T1DM). Objective: To evaluate electrocardiographic markers of arrhythmias in T1DM patients. Methods: Electrocardiographic parameters reflecting ventricular depolarization and repolarization...

Long-Term Mortality in Cardioinhibitory Carotid Sinus Hypersensitivity Patient Cohort

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: Cardioinhibitory carotid sinus hypersensitivity (CICSH) is defined as ventricular asystole ≥ 3 seconds in response to 5-10 seconds of carotid sinus massage (CSM). There is a common concern that a prolonged asystole episode could lead to death directly from bradycardia or as a ...

COVID-19 and acute myocarditis: current literature review and diagnostic challenges

Rev Assoc Med Bras (1992); 66 (Suppl 2), 2020
SUMMARY INTRODUCTION In the current literature, there has been an upsurge of cases of COVID-19-induced acute myocarditis. In this case-based review, we aimed to describe the clinical characteristics, imaging findings, and in-hospital course of acute myocarditis. In addition, the limitations of the myoc...

Chagas disease in Virgem da Lapa, Minas Gerais, Brazil: left ventricle aneurysm and the risk of death in the 24-year interval

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Left ventricular aneurysm (LVA) is indicator of high morbidity in Chagas' disease. A cross-sectional study performed identified LVA in 18.8% of the chronic chagasic patients (CCP). OBJECTIVE Determine the risk of death of patients with chronic chagasic cardiopathy (CCC) and LVA in 24-year in...

Antiparasitic and anti-inflammatory activities of ß-lapachone-derived naphthoimidazoles in experimental acute Trypanosoma cruzi infection

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Chagas disease, which is caused by the protozoan Trypanosoma cruzi, is endemic to Latin America and mainly affects low-income populations. Chemotherapy is based on two nitrocompounds, but their reduced efficacy encourages the continuous search for alternative drugs. Our group has characterise...

Determination of the increased risk of developing atrial fibrillation in fibromyalgia syndrome

Adv Rheumatol; 60 (), 2020
Abstract Introduction: Atrial fibrillation (AF) is the leading cause of ischemic stroke and is one of the most common arrhythmias. Previous studies have shown that impaired diastolic functions, P wave dispersion (Pd), and prolonged atrial conduction times (ACT) are associated with increased incidence of...
