Why the study?
What are the hemodynamic mechanisms underlying orthostatic and haemorrhagic fainting in healthy young men?
What are the hemodynamic mechanisms underlying orthostatic and haemorrhagic fainting in healthy young men?
Fainting appears to be precipitated by a reflex control of the filling volume/pressure of the heart that counteracts arterial blood pressure regulation.

Identifies reflex-mediated syncope trigger via cardiac filling pressures in young men; hypothesis-generating and leaves generalizability open.
Bergenwald et al. (1977) studied this question.
