Magnetocardiography and exercise testing
Journal of Electrocardiology, 1994Twenty healthy male subjects (age range, 15-25 years; median, 21 years) underwent magnetocardiography during physical exercise. Significant ST-segment displacements of the magnetic signal were found during exercise at a heart rate of 120 beats/min compared to the magnetic signal at rest (P < .001).

Veterinary Clinics of North America: Equine Practice, 1985
In the athletic horse, an exercise test may be required to measure the adaptation of the animal to a specific training program; to modify the training program in response to the progress achieved; to investigate the reasons for failure to perform at the expected level; and to form part of an overall clinical examination of a horse with a specific ...

Exercise Testing for Sports and the Exercise Prescription
Cardiology Clinics, 1987The uses of the exercise test continue to grow and diversify. Familiarity with the mechanics, logistics, and interpretation of these tests leads to their optimal use. The application of exercise testing for competitive or recreational sports, cardiovascular fitness exercise training, and cardiac rehabilitation is the focus of this review.

Arrhythmia With an Exercise Test
The American Journal of Cardiology, 2020A 64-year-old man with known coronary disease presented to the hospital with sinus bradycardia, chest pain, and normal cardiac enzymes. During an exercise stress test he developed ventricular fibrillation that spontaneously resolved.

Cardiology Clinics, 1984
The normal hemodynamic response to dynamic supine exercise embodies the following features: progressive increase in heart rate relative to the work intensity; an increase in cardiac output of 600 ml or greater for every 100-ml increment in oxygen consumption; minimal increase in stroke volume; a progressive increase in oxygen extraction, attaining near-

The phonocardiogram exercise test
IEEE Engineering in Medicine and Biology Magazine, 1999Cardiovascular disease is the leading killer and the major cause of disability in adults. Detection and analysis of heart sounds is an important (and economical) method that can be used to determine the state of the heart and great vessels. In this article we present a newly developed technique for detecting cardiac reserve in both healthy and diseased

To the Editor. —The Editorial entitled "Isometric Exercise Testing: Usefulness and Limitations" by Dr Stefadouros, published in the JanuaryArchives(1983;143:26-27), began with a statement that brought me up short: "... Isometric exercise [is] a form of exercise where the contracting muscles develop force without shortening." Can this be so?

Current Opinion in Cardiology, 1991
The number of diagnostic modalities available to the pediatric cardiologist continues to escalate. However, with so many choices, it is often difficult to know what test is most efficacious in a given situation or how often to repeat it. This review summarizes the data from several exercise studies published within the past year.

Cardiopulmonary Exercise Testing
Clinics in Chest Medicine, 1989Cardiopulmonary exercise testing is an objective method of assessing the functional capacity of a patient. In contrast to clinical assessment and resting investigations, exercise testing is useful in detecting early changes in patients with cardiac or respiratory disease.

Neurology, 1979
The response to a standardized exercise test was investigated in 12 volunteers and 13 patients with aches, cramps, and pains. In men, creatine kinase (CK) levels peaked (up to 1600 mU per milliliter) between 10 and 20 hours after exercise. High levels of blood lactate during exercise were related to the intensity of work and to high levels of CK after ...
