这些都是心脏彩超报告单中的一些重要测量值的英文缩写：LVED 是左室舒张末内径，LVES是左室收缩末内径，LA是左房大小，AO是主动脉内径，RV是右室的意思，RVOD是右室流出道，PA是肺动脉，E/A是EA比，HR是心率的意思，FS是短轴缩短率，EF是射血分数，等等，通过这些数值可以反映出心脏结构及功能的情况，如果你看不懂，说明你这方面的知识欠缺较多，需要找些专业书看，否则你仅知道这些缩写的意思也没多大“意思”。

英语中的时态呼应就是在主句时态为“非现在时”时，从句的时态必须与主句相呼应。其规则如下： 1.主句谓语为现在时或者将来时态，从句中的谓语时态可以不受影响，即按照意思决定时态。如： It is reported that they are building a new railway. 【is表示主句的谓语动词是现在时，从句的谓语动词是are，没有影响】Will you please tell us how you got to knwo it?
