          Abstract

          In 20 patients a method for left-to-right shunt calculation based on precordial radiocardiographíc curves after in- dicator (RISH) injection into the antecubital vein was compared with arterial dye (Ujoviridin = Cardio Green) dilution curves. There was adequate correlation between the values obtained from radiocardiographic and dye dilution curves: mean values 57.4 and 57.8% of the pulmonary flow, r = 0.71, mean difference 0.4, s<sub>D</sub> = 17.5. The left ventricular build-up time imaginary on radiocardiographic curves was derived from the (constant) relation between build-up time and maximum concentration time.
