title: [Clinical evaluation of cardiac function test using scintiview (author's transl)].
abstract: Cardiac function was studied with Scintiview in 107 cases, 24 normal and 83 affected cases, and the following results were obtained. 1. Better data were obtained with converging collimeter than with parallel collimeter in cardiac study. (2) Red blood cells were sufficiently labeled with 99mTc using stannous chloride as reductant, and it was proven to be applicable to measurement of circulation blood volume. (3) Pulmonary circulation time and the systemic circulation time calculated from time activity curve, greater than 9.0 seconds and greater than 25 seconds, respectively, were considered abnormal prolongation. (4) Cardiac output index (cardiac output/circulation blood volume), less than 1.10 was considered decreased cardiac output. (5) Stroke volume index ((stroke volume/circulation blood volume)x 100, less than 1.70 was considered decreased stroke volume. (6) Ejection fraction, less than 60% was considered decreased left ventricular wall motion. (7) Cardiac function index (cardiac output index X ejection fraction), less than 80 was considered decreased cardiac performance.
