Can continuous wave Doppler echocardiography accurately measure cardiac output and track hemodynamic changes during maximal treadmill exercise?
Continuous wave Doppler echocardiography from the suprasternal notch is a feasible and accurate non-invasive method for monitoring cardiac output and hemodynamic changes during maximal treadmill exercise.
