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...
متن کاملThe 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 کاملLeft precordial isopotential mapping during supine exercise.
Junctional depression is often observed during physical exercise in overtly normal subjects. To explore its pathogenesis, 15 normal volunteers were studied during supine, bicycle ergometer, submaximal stress tests. Electrocardiograms were simultaneously recorded from 42 electrodes on the left anterior precordium at two minute intervals at rest and during exercise. Data were used to construct is...
متن کاملPrecordial T wave Inversions on Electrocardiogram
T wave inversions on an electrocardiogram (EKG) can manifest from any process that result in a relative delay in regional ventricular repolarization. The differential diagnosis of right precordial T wave inversions, leads V1-V3, include myocardial ischemia, a normal athlete’s heart, arrhythmogenic right ventricular dysplasia, and pulmonary embolism amongst others. The case discussed below is of...
متن کاملThe precordial electrocardiogram in incomplete right bundle branch block.
I N 1917 Rothberger and Winterberg’ published an electrocardiographic record which depicts the gradual clearing of a defect in conduction affecting the right branch of the bundle of His. An attempt to cut this structure in the course of an experiment on a dog blocked it only temporarily. Fortunately, one of the tracings taken spanned the period during which the injured bundle gradually recovere...
