These animal data provide no basis for changing clinical potassium or calcium management; hypothesis-generating for myocardial ion handling.
In isolated rabbit hearts, potassium efflux into a potassium-free solution approximates K42 equilibration and is unaffected by doubling perfusate calcium.
Edward W. Humphrey (1961) studied this question.
