Published in Medical Imaging Week, August 4th, 2007

According to recent research from Beijing, People's Republic of China, "The effect of acute hypoxia on the human left ventricular function during exercise was evaluated by 2D and Doppler echocardiography on 11 healthy male college students. Each subject completed 6-min moderate intensity (100 W) supine cycling exercises in normoxia and hypoxia, respectively."

"The concentration of inspired O-2 was adjusted to keep arterial hemoglobin O-2 concentration (SpO(2)) at 88-92% during hypoxia. Doppler indices obtained were compared between normoxia and hypoxia. The left ventricular myocardial diastolic function was increased during exercise in hypoxia compared with normoxia....
