The Electrocardiogram During Exercise
ELECTROCARDIOGRAPHIC (ECG) recording during exercise, employed for years by work physiologists, has only recently arrived on the scene of cardiovascular investigations in clinical, epidemiological, and sports medical areas. This has come about from interest in the import of ECG events observed during activity, from the improved safety provided by monitoring performance tests, and from technical...
متن کاملThe precordial electrocardiogram during exercise.
C ONTINUOUS recording of the precordial electrocardiogram during vigo-ous exereise has been tested in 150 persons through the use of a new lead system, a new method of electrode attachment, and special types of electrodes and electrode paste. This technic has resulted in tracings that are almost free of skeletal muscle potentials and baseline shift in subjects performing the Master's 2-step tes...
متن کاملExercise Electrocardiogram in Myxoedema
An unexpectedly high incidence of abnormalities in the sulphobromophthalein (Bromsulphalein) excretion test, and to a smaller extent in other tests of liver function, was found in patients taking allopurinol and in those on uricosuric treatment. The reason for this is not apparent, but there is no evidence that either type of drug treatment was responsible. It is as yet uncertain whether allopu...
متن کاملCardiac monitoring during exercise tests in the horse. 3. Changes in the electrocardiogram during and after exercise.
Changes that occur in the equine ECG during and after exercise have been described and compared with resting ECG's obtained from the same horses. When the speed of work equals or is greater than "three-quarter pace" (i.e. "even time" or 200 metres in 15 seconds) the high heart rates developed cause the loss of ECG waveforms that are readily discernible at rest. Although differences in the wavef...
متن کاملThe electrocardiogram during angiocardiography.
It is often said that angiocardiography carries little risk, and series of more than a thousand injections without a death are on record (Sussman, 1948; Horger et al., 1951). During recent years, however, more than thirty deaths have been reported-the majority in children with cyanotic congenital heart disease. The exact cause of these deaths has still to be discovered. When Mr. R. C. Brock beg...
