Effect of Supine Exercise
RESPONSE to physical exercise in man has been studied extensively. For any given workload, a predictable change in blood pressure, heart rate, and cardiac output has been shown to occur. Rushmerl has pointed out that the response of stroke volume to exercise, however, may be variable both in experimental animals and in man. He has also demonstrated that not only the amount, but also the directi...

متن کاملAccuracy of automated auscultatory blood pressure measurement during supine exercise and treadmill stress ECG-testing
Objectives Monitoring of brachial blood pressure during exercise-ECG testing is mandatory and changes in blood pressure (BP) can provide critical management evidence. Patient movement, mechanical vibration, artifactual sounds and observer variability make standard manual techniques problematic. This was an investigator-initiated study to assess an automated auscultatory technique of BP assessme...
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 کاملLeft Ventricular Volume During Maximal Supine Exercise:
Changes in left ventricular (LV) volumes and ejection fraction between rest and maximal supine exercise were evaluated in 11 patients who had had four epicardial markers placed during coronary artery surgery. After calibrating marker distances with respect to volume (r = 0.92-0.99) over one cardiac cycle for each patient, regression equations were used to compute LV volume from marker measureme...
