Therefore, we see that an increase in end-diastolic volume, or 'preload, ' results in an increased stroke volume.

因此，我们看到舒张末期容积或" 预负荷" 增加导致每博输出量增加。

Two scientists named Frank and Starling noticed that the increase in end-diastolic volume, or preload, results in an increased stroke volume and more blood being pumped out of the heart with each heartbeat.

两位名为Frank和Starling的科学家注意到，舒张末期容积（即预负荷）的增加导致每搏输出量增加，并且每次心跳都会将更多的血液从心脏中泵出。
