Abstract
In 1948, Eckenhoff et al. [1] described a method of measuring coronary flow based on the principle that an inert gas (nitrous oxide) diffuses across the capillary membrane in proportion to the rate of coronary flow. A concentration curve was obtained by sampling from the coronary sinus and by applying the Fick principle, myocardial flow may be calculated. Several different gases have been employed (H-2 helium, argon and radioactive xenon-133) with arterial or coronary venous sampling to construct desaturation curves.
