Radioelectrocardiographic Changes during Strenuous Exercise

چکیده
T HE TYPE AND AMOUNT of exercise recommended for the electrocardiographic diagnosis of coronary artery disease have been a matter of discussion and some controversy.' The electrocardiogram has also been studied after extreme effort, such as long-distance running,2 skiing,3 rowing,4 strenuous marching,5 and other forms of sports.6 7 Master and Oppenheimer in 19298 described a standardized two-step exercise test that has gained wide popularity for the diagnosis of coronary artery disease. Other forms of standardized exercise such as walking on a treadmill9' 10 or riding a bicycle"l-13 have also been used. With a few exceptions,11-17 most studies on the effect of exercise on the electrocardiogram deal with the period after exercise. The recently introduced radioelectrocardiograph eliminates most of the difficulties of recording electrocardiograms during exercise.18-23 We have previously described the changes that occur during the Master two-step test in normal subjects as well as in patients with hypertensive or arteriosclerotic cardiovascular disease23' 24 and in patients with angina pectoris.24 Here, are presented the changes that occur in normal individuals during the performance of exercise more strenuous than the Master test.

Time-dependent mobilization of circulating progenitor cells during strenuous exercise in healthy individuals.
Exercise stimulates the release of hematopoietic and endothelial progenitor cells (EPC) from the bone marrow. However, no data are available concerning the time frame of EPC release during strenuous exercise. The aim of the present study was to investigate the time-dependent release of progenitor cells during strenuous exercise. Eighteen healthy young men cycled for 4 h continuously at 70% of t...

In a longitudinal study we investigated some cardiovascular responses to strenuous bicycle exercise in 33 healthy women during pregnancy and the postpartum period. The exercise electrocardiogram demonstrated depression of the ST segment in 12% of women in the absence of clinical signs of ischemia, and the incidence of these changes was unaffected by pregnancy. In spite of slightly different blo...
