Exercise electrocardiogram patterns in normal women.

Exercise 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...

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...

The normal composite electrocardiogram.

The normal electrocardiogram.

O NE of the most difficult tasks which confronts the w orker in the life sciences is to define a normal. The difficulty is compounded when the measurement to be made is affected by many variables which differ in importance from time to time. These remarks apply to the electrocardiographer, and to the normal electrocardiogram. Some variables which affect the electrocardiogram are quite well know...

The 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...
