摘要：

Inm radiocardiography in conjunction with a gamma camera and a digital computer is applied to measurements of cardiac output, stroke volume, ejection fraction, end-diastolic volume, pulmonary blood volume, pulmonary transfer time and dispersion both at rest and during muscular exercise. A modified gamma function is used in calculations of radiocardiographic curves. In twelve supine male subjects the maximal increase of cardiac output was 220% stroke volume 30% ejection fraction 15% and pulmonary blood volume 30% The present method provides a non-invasive tool for cardiovascular examinations during exercise. © 1979 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
