Venous Physiology: The Overlooked Key to Syncope and The Regulation of Cardiac Output

Abstract

Kenneth M. Eyer

As the years go by, the physiology of the human body becomes ever better understood. But because venous tone cannot easily be measured it is no wonder the physiology of veins has been consistently overlooked. The author describes his experiences suggesting the key role it appears to play in vasovagal syncope, the regulation of cardiac output, high altitude pulmonary edema, beri-beri, and in those with cardiac arrest.
