title: The relationship between oxygen extraction and extravascular mean transit time in the canine heart.
abstract: A significant relationship was observed between myocardial oxygen extraction and the extravascular mean time transit time. This relationship implies that oxygen extraction by the myocardium is a time-dependent process, and emphasizes the critical link between blood flow and myocardial oxygen consumption.
