The effects of exercise and subject age on pulsed Doppler measurements of left ventricular ejection in normal man.

Pulsed Doppler measurements of ascending aortic blood velocity and acceleration were made in a group of normal subjects on exercise. The aims of the study were: (1) to document the normal response to exercise and its variability at various ages as a baseline for future studies in abnormal subjects, and (2) to investigate the accuracy and reproducibility of… CONTINUE READING
