射血分数为一重要的心功能指标,但在小动物心脏上难以测定。本文介绍了在大鼠离体工作心脏灌流模型上用染料稀释法测定心脏射血分数的简便方法。该方法可靠、重复性强,可在同一心脏上反复测量。
Ejection fraction is an important cardiac function, but difficult to measure in the heart of small animals. This article presents a simple and convenient method for the determination of cardiac ejection fraction using the Dilution Dilution Method in an isolated working cardiac perfusion model in rats. The method is reliable, reproducible and can be repeatedly measured on the same heart.
