Amongst one hundred patients examined radiographically, segmental early relaxation (SERP) of the antero-lateral wall of the left ventricle was observed in 21 cases; in 17 cases this was associated with a significant stenosis of the anterior descending branch of the left coronary artery. The reversibility of this phenomenon produced by vaso-dilators or by aorto-coronary by-pass operations with consequent increase in oxygen supply, as well as the frequency of this phenomenon in coronary disease suggests that it is due to mild, local hypoxia. On this view, SERP has clinical significance as an angiographic indicator of local oxygen deficit. Other possible causes are discussed and the findings compared with those reported in the literature.
在100例接受影像学检查的患者中，21例观察到左心室前侧壁节段性早期松弛（SERP）；其中17例与左冠状动脉前降支的明显狭窄有关。血管扩张剂或主动脉冠状动脉搭桥手术导致的氧供应增加所产生的这种现象的可逆性，以及这种现象在冠心病中的发生频率表明，它是由轻度局部缺氧引起的。据此观点，SERP作为局部氧缺乏的血管造影指标具有临床意义。文中讨论了其他可能的原因，并将研究结果与文献报道的结果进行了比较。
