The changes of P loops mentioned above were caused by the electrical changes in the atrium which were due to the corresponding dilation of the left atrium caused by the sudden decrease of the pumping function of the heart when AMI occurred. 上述P环变化是因为AMI时心脏泵血功能骤减引起相应的左心房扩张造成的心房电学变化。提示:急性心肌梗塞P环异常与左心早期功能不全有关。
Objective: To evaluate the affects of giant left atrium ( GLA) and the benefits of left atrial plication ( LAP) on the recovery of heart and lung function during early postoperative stage. 目的分析巨大左心房对二尖瓣瓣膜手术后早期心肺功能恢复的影响,以及左心房折叠术(LAP)的早期手术疗效。
