| Research Abstract |
Cardiac performance during exercise was evaluated using novel echocardiographic techniques in normal subjects. All datasets from parasternal views were obtained. Speckle tracking imaging datasets from apical views were analyzed in 8 of 10 subjects. During exercise, cardiac output and E/e' increased with exercise stress. On the other hand, stroke volume and global systolic strain did not change with exercise. Cardiac performance during exercise can be evaluated, and has potential for clinical applications.
