1. Effect of artemisinin-piperaquine treatment on the electrocardiogram of malaria patients
Abstract INTRODUCTION: Concern regarding the cardiotoxicity of antimalarials has been renewed because of their potential to cause QT/QTc interval prolongation related to torsade de pointes (TdP). Artemisinin-piperaquine (AP) is considered an effective artemisinin-based combination therapy (ACT) for malaria. METHODS: This study involved a retrospective an

2. Athlete’s heart in a Brazilian paralympic judo team. Case series study
ABSTRACT BACKGROUND: Athlete’s heart is a term describing the cardiovascular effects of long-term conditioning among highly trained athletes. It is a variation of normal standards. DESIGN AND SETTING: Case series study at the cardiology division of a public university hospital. METHODS: We studied 14 visually handicapped paralympic athletes (8 men) i

3. Surveillance of seroepidemiology and morbidity of Chagas disease in the Negro River, Brazilian Amazon
BACKGROUND Chagas disease in the Brazilian Amazon Region was previously regarded as an enzootic disease of wild animals. More recently, in situations where humans have penetrated the wild ecotope or where triatomines and/or wild animals (marsupials) have invaded human homes resulting in disease transmission, Chagas disease has come to be regarded as an anth

4. Prevalence of electrocardiographic abnormalities in primary care patients according to sex and age group. A retrospective observational study
ABSTRACT BACKGROUND: Knowledge of the prevalence of electrocardiographic abnormalities in a population is useful for interpreting the findings. The aim here was to assess the prevalence of electrocardiographic abnormalities and self-reported comorbidities and cardiovascular risk factors according to sex and age group among Brazilian primary care patients.

6. Spirometry reference values in the Brazilian population
The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and averag

7. Heartbeat classification system based on neural networks and dimensionality reduction
Abstract Introduction This paper presents a complete approach for the automatic classification of heartbeats to assist experts in the diagnosis of typical arrhythmias, such as right bundle branch block, left bundle branch block, premature ventricular beats, premature atrial beats and paced beats. Methods A pre-processing step was performed on the electroca

8. Premature ventricular contractions associated with isotretinoin use
Abstract Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions. This report describes a 33-year-old-woman who presented with palpitations for 1 week while undergoing 1-month isotretinoin treatment for mild-moderate facial acne. An

9. Outbreak of acute Chagas disease associated with oral transmission in the Rio Negro region, Brazilian Amazon
Introduction Chagas disease is considered as emerging in the Brazilian Amazon, usually occurring in acute outbreaks. Methods We describe 17 cases of acute Chagas disease in Rio Negro, Amazonas. Results There were 15 males (average age, 31.3 years), all positive for Trypanosoma cruzi in fresh blood smear examination, and 14 positive by xenodiagnosis and

10. C-Reactive protein predicts acute myocardial infarction during high-risk noncardiac and vascular surgery
BACKGROUND: High-sensitivity C-reactive protein predicts cardiovascular events in a wide range of clinical contexts. However, the role of high-sensitivity C-reactive protein as a predictive marker for perioperative acute myocardial infarction during noncardiac surgery is not yet clear. The present study investigated high-sensitivity C-reactive protein levels

11. Compression of electrocardiograms using wavelets / Compressão de eletrocardiogramas usando wavelets
A principal contribuição desta dissertação é a proposta de dois métodos de compressão de eletrocardiogramas (ECGs). O primeiro método, chamado Run Length Encoding Adaptativo (RLEA), é baseado nas transformadas wavelet e consiste basicamente em utilizar uma função wavelet, obtida pela resolução de um problema de otimização, que se ajuste ao sin

12. Visualização e simulação de sinais cardiológicos utilizando técnicas de realidade aumentada
Nowadays, the presence of computers is noted, even subtle, in almost every area of human knowledge and activity. The advantages emerged by computers are many, but there are still drawbacks that need efficient solutions. The tech devices and audiovisual ways of communication between the user and computers are still a great challenge, because to use successful
