Objective To evaluate the alteration and clinical significance of left ventricular volume ( LVV) in patients with coronary artery disease ( CAD) during dobutamine stress testing ( DST).

目的评价多巴酚丁胺负荷试验（DST）中冠心病（CAD）病人左室容积（LVV）的变化及临床意义。

Conclusions Tri-plane can accurately quantify LVV and the method is superior to 2DE-Simpson in evaluating LVV.

结论Tri-plane法可准确测量正常心腔及心腔变形情况下的左心室容积，该方法测量容积的准确性优于2DE-Simpson法。

Methods The left ventricular volume ( LVV) in32 cases of normals and35 patients with MI were measured by using DST.

方法用3DE方法测定了32例正常人和35例急性MI恢复期患者在DST中的变化情况。
