Abstract

After acute myocardial infarction there is a shortening of the QS2 interval and the ejection time. The pre-ejection time is either normal or prolonged. After the stage of maximum shortening of the QS2 interval and ejection time, there is a progressive improvement towards the normal. In this study there was no correlation between the shortened QS2 interval and ejection time, and the level of urinary catecholamine excretion. The physiological and clinical significance of these changes in the systolic time intervals and their relation to the altered haemodynamics and mechanics are discussed.

摘要

急性心肌梗死后，QS2间期和射血时间缩短。射血前期时间正常或延长。在QS2间期和射血时间最大程度缩短阶段之后，会逐渐向正常水平改善。在本研究中，缩短的QS2间期和射血时间与尿儿茶酚胺排泄水平之间无相关性。文中讨论了收缩期时间间期这些变化的生理和临床意义，以及它们与血流动力学和力学改变的关系。
