It is a matter of the circumstances surrounding the syncope. In vasovagal they are having a BM or doing something to stimulate their vagal tone.
In this case, she is exercising and can not increase her cardiac output to respond to the increased demand due to a fixed outlet obstruction (i.e. aortic stenosis)
