1. QT Interval Dispersion Behavior in Patients With and Without Obstructive Coronary Artery Disease Undergoing Exercise Test
Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased heterogeneity of ventricular repolarization measured by dQTc.

Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased heterogeneity of ventricular repolarization measured by dQTc.

3. Evolution of potential biomarkers of acute muscle injury after physical exercise
Skeletal muscle injury is a frequent event and diagnosis using the classical blood markers sometimes produces unsatisfactory results. Therefore, objective of the study was to detect new biomarkers in plasma, saliva and urine in response to acute muscle damage induced by physical exercise. A cross-sectional study was conducted with 27 American football player

4. Analysis of agreement between cardiac risk stratification protocols applied to participants of a center for cardiac rehabilitation
ABSTRACT Background Cardiac risk stratification is related to the risk of the occurrence of events induced by exercise. Despite the existence of several protocols to calculate risk stratification, studies indicating that there is similarity between these protocols are still unknown. Objective To evaluate the agreement between the existing protocols on card

5. Broncoespasmo induzido pelo exercício em crianças e adolescentes com diagnóstico de asma / Exercise-induced bronchospasm in children and adolescents with a diagnosis of asthma
Introdução: A broncoconstrição temporária após o exercício físico tem elevada prevalência em crianças e adolescentes asmáticos. Objetivo: Determinar a freqüência e gravidade do broncoespasmo induzido pelo exercício em crianças e adolescentes, com diagnóstico clínico de asma leve, moderada e grave. Método: Foi realizado um estudo descritivo,

6. Diagnosis of Pneumocystis carinii pneumonia in HIV antibody positive patients by simple outpatient assessments.
BACKGROUND: As increasing numbers of patients with immunosuppression induced by the human immunodeficiency virus (HIV) present with respiratory symptoms it is important to differentiate Pneumocystis carinii pneumonia from other chest diseases rapidly and start treatment early. The management of pneumocystis pneumonia could be improved if clinicians could dia

7. Prevalence of asthma and wheeze in the Highlands of Scotland.
To establish the prevalence of asthma and wheeze in 12 year old children in a region with low background pollution levels, a population of children resident in the Highland Region of Scotland was studied by questionnaire supported by objective data. A respiratory questionnaire was distributed to the parents of 1919 children aged from 12-13 years and attendin

8. The use of transcutaneous oxygen tension measurements in the diagnosis of peripheral vascular insufficiency.
Transcutaneous tissue oxygen tension (PtcO2) was evaluated as a noninvasive diagnostic test for peripheral arterial insufficiency; PtcO2 was measured at rest, during exercise, and following exercise at three leg sites in 36 controls and 138 patients with exercise-induced leg pain. Resting foot PtcO2 differed significantly in controls and in patients with res

9. The Accuracy of Exercise-Induced ST Segment Elevation as a Sign of Left Ventricular Aneurysm
In 3,108 consecutive treadmill exercise tests, ST segment elevation developed or increased over its value at rest in 47 patients (1.5%) in the area of a previous myocardial infarction. Left ventricular angiograms were performed in all cases. A left ventricular aneurysm was found in 39 of the 47 patients (83%), akinesis in four patients (8.5%), and hypokinesi

10. Application of conditional probability analysis to the clinical diagnosis of coronary artery disease.
Analysis of multiple noninvasive tests offers the promise of more accurate diagnosis of coronary artery disease, but discordant test responses can occur frequently and, when observed, result in diagnostic uncertainty. Accordingly, 43 patients undergoing diagnostic coronary angiography were evaluated by noninvasive testing and the results subjected to analysi

11. Impaired left ventricular filling dynamics in patients with angina and angiographically normal coronary arteries: effect of beta adrenergic blockade.
OBJECTIVE: To assess exercise performance and resting left ventricular filling dynamics in patients with syndrome X (SX) in basal conditions and after 10 days treatment with oral atenolol. DESIGN AND PATIENTS: Exercise performance was studied and left ventricular filling assessed by Doppler-derived transmitral flow pattern analysis in 22 patients (16 female,

12. Changes in the electrocardiographic response to exercise in healthy women.
Changes in the P wave, QRS complex, ST segment, and T wave during and after maximal exercise were quantitatively analysed in 116 healthy women with a mean age of 39. The corrected orthogonal Frank lead electrocardiogram was continuously recorded and computer processed during bicycle ergometry. With exercise, maximal spatial P wave vectors shifted downward. T
