50 patients were investigated by both left ventricular cine-angiography, and "balanced" gamma-cine-cardiography in the frontal and LAO positions. Measurements of the ejection fraction and the mean and maximal speeds of contraction were made by the two techniques. The correlation was good (r = 0.89 for the ejection fraction). A morphological analysis of the dynamic findings in the two methods in the 12 cases with discordered left ventricular kinetics showed that once again the results were very similar. A numerical presentation of the data from the radioisotope studies was made either as a group of sequential ventricular contours successively from diastole to systole, or to give a functional picture which would provide the value for one kinetic paramter at any one time (for example, the regional equivalent of the ejection fraction). To overcome the problems of superimposition in the RAO position in the "balanced" technique, the recordings of the first radioisotope study in RAO were combined with a study of balance in 50 other patients, and the correlation was excellent. These two isotope techniques, which can be carried out in the same examination and which may be repeated without risk, perfectly complement each other, and very few of the results were incapable of interpretation.
对50例患者进行了左心室电影血管造影以及在前位和左前斜位的“平衡”γ电影心动图检查。通过这两种技术测量射血分数以及平均和最大收缩速度。相关性良好（射血分数的r = 0.89）。对12例左心室动力学紊乱患者的两种方法的动态结果进行形态学分析表明，结果再次非常相似。放射性同位素研究数据的数字呈现方式，要么是一组从舒张期到收缩期连续的心室轮廓，要么是给出一个功能图像，该图像可在任何时刻提供一个动力学参数的值（例如，区域等效射血分数）。为克服“平衡”技术中右前斜位的叠加问题，将右前斜位首次放射性同位素研究的记录与另外50例患者的平衡研究相结合，相关性极佳。这两种同位素技术可在同一次检查中进行，且可无风险地重复，它们完美互补，几乎没有结果无法解释。
