1. Heart rate turbulence assessed through ergometry after myocardial infarction: a feasibility study
ABSTRACT BACKGROUND: Coronary artery disease is an important cause of morbidity and mortality. The impact of ventricular arrhythmias with impaired cardiac vagal activity is one of the most recently studied prognostic factors. However, there are no studies evaluating the phenomenon of heart rate turbulence (HRT) during physical exertion. OBJECTIVE: To stu

2. A practical approach to assess leg muscle oxygenation during ramp-incremental cycle ergometry in heart failure
Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (deoxi-Hb) as measured by near-infrared spectroscopy (NI

3. Diretriz Sul-Americana de Prevenção e Reabilitação Cardiovascular
In this document, the Inter-American Committee of Cardiovascular Prevention and Rehabilitation, together with the South American Society of Cardiology, aimed to formulate strategies, measures, and actions for cardiovascular disease prevention and rehabilitation (CVDPR). In the context of the implementation of a regional and national health policy in Latin Am

4. Acurácia do teste ergométrico no diagnóstico da reestenose coronariana após angioplastia com implante de Stent convencional em pacientes assintomáticos
A detecção da reestenose intrastent é importante na prática clínica fornecendo informações úteis para a orientação terapêutica. Os objetivos deste estudo foram, avaliar a eficácia do teste ergométrico (TE) na detecção de reestenose após angioplastia transluminal coronariana com implante de stent convencional (ATC-stent), comparando este méto

5. High cardiorespiratory fitness is more beneficial in pre-diabetic men than women
OBJECTIVES: To investigate gender-specific relationships between cardiorespiratory fitness and factors that predict the development of diabetes and to identify the risk factors that predict fasting plasma glucose and 2-hour plasma glucose levels. INTRODUCTION: Different risk factors (e.g., low cardiorespiratory fitness) may cause elevated plasma glucose leve

6. Validação de uma bicicleta ergométrica de ciclismo indoor
The adaptation of load system an bicycle ergometer for indoor cycling (BEIC) allowed its classification as an cycle ergometer, however, its validation must be tested. Because of this it was decided to test the validation of BEIC and the contested Monark. Forty and two cyclists of a regional level (Mean-DP): age 33,7 (8,4) years; stature 175,3 (6,3) cm; body

7. "Definição de conduta na investigação de doença coronária obstrutiva utilizando teoria de conjuntos fuzzy aplicada a dados clínico-epidemiológicos, ergométricos e cintilográficos" / Establishment of diagnostic procedures for coronary artery disease based on fuzzy set theory applied to clinical epidemiological data and treadmill electrocardiography and myocardial perfusion scintigraphy results.
Coronary artery disease (CAD) is a worldwide leading cause of death. Early detection is important to prevent such sort of outcome. The gold standard method for evaluating critical partial occlusions is coronary arteriography, a catheterization technique which is invasive, time consuming, and costly. There are noninvasive approaches for early detection of CAD

10. Estudo dos ajustes cardiorrespiratorios ao exercicio fisico dinamico em adolescentes
The main goal of this study is to evaluate the behaviour of instantaneous heart rate and oxygen comsumption in the continuous exerci se protocol. Ten (10) male adolescents ranging ITom 12 to 15 years old, on stage 5 of sexual maturation, not participating in any regular physical training program, were studied. All volunteers were submitted to: 1) antropometr

11. Comparison of arm and leg ergometry in patients with moderate chronic obstructive lung disease.
Exercise testing is traditionally performed with leg exercise on either a treadmill or a bicycle ergometer. Many of these tests are terminated before dyspnoea occurs because of leg fatigue, arthritic pain, or claudication. A study was carried out to determine whether arm ergometry testing might serve as an alternative method to leg testing in eight patients

12. Oxygen desaturation and breathlessness during corridor walking in chronic obstructive pulmonary disease: effect of oxitropium bromide.
BACKGROUND--Although exercise induced desaturation can occur in patients with chronic obstructive pulmonary disease (COPD), little is known about its frequency during everyday exercise, or how it relates to dyspnoea or prior drug treatment. METHODS--The effects of 200 micrograms inhaled oxitropium bromide, an anticholinergic bronchodilator drug, on spirometr
