This study observed the left function in determining filling dynamics of the left ventricle in patients with myocardial infarction. The study consisted of eight control subjects and ten patients with myocardial infarction. The left ventricular filling volume is considered to be composed of the left atrial passive emptying, active emptying, and conduit volumes. The change of left ventricular filling volume was correlated with that of conduit volume (r = .87, P less than .01). However, the change of left ventricular filling volume did not have any correlation to those of left atrial passive emptying and active emptying volumes. These results suggested that the left atrial conduit function was important in determining filling dynamics of the left ventricle.
本研究观察了左心房功能在确定心肌梗死患者左心室充盈动力学中的作用。该研究包括8名对照受试者和10名心肌梗死患者。左心室充盈量被认为由左心房被动排空、主动排空和管道容量组成。左心室充盈量的变化与管道容量的变化相关（r = 0.87，P < 0.01）。然而，左心室充盈量的变化与左心房被动排空量和主动排空量的变化无任何相关性。这些结果表明，左心房管道功能在确定左心室充盈动力学中很重要。
