[New possibilities of the thermodilution method in studying coronary circulation and intracardiac hemodynamics].
The new possibilities of determining the coronary blood flow and intracardiac hemodynamics by the thermodilution method were studied in experiments on 40 mongrel dogs. A method for measuring the true coronary blood flow without catheterization of the coronary arteries and coronary sinus as well as a modified Holt's method for determining the end diastolic volume of the heart ventricles are suggested. The method is simple and therefore creates favourable prospects for its wide use both in experiments and in clinical studies.
