We saw an improvement in the ejection fraction, in the ability of the heart to pump out blood, of 25%.

Purpose: To compare gated myocardial perfusion tomography (GMPT), gated blood pool imaging (GBPI) and ultrasound cardiography (UCG) in left ventricular ejection fraction (LVEF) calculation.

目的：探讨门控心肌灌注断层显像（GMPT）、平衡法心血池显像（GBPI）与心动超声（UCG）测定左室射血分数（LVEF）的差别。

Conclusions the results showed that the value of blood output of heart in the rapid ejection period measured by the non linear formula may reflect the basic rule of the ejection of heart.

结论非线性公式计算心脏快速射血期的排血量和时间参数能够反映心脏射血的基本规律。
