9、功能不全如何發(fā)發(fā)生？心 1、心肌收縮縮力 2、心臟臟舒張順應張順應性 3、心率心肌頓頓抑 是指心肌短時間缺血后不發(fā)生壞死，但引起心肌細細胞的結(jié)結(jié)構(gòu)構(gòu)、代謝謝和功能改變變在再灌注后延遲遲恢復復的現(xiàn)現(xiàn)象 臨床特征表現(xiàn)為收縮縮功能障礙 持續(xù)數(shù)數(shù)天到數(shù)數(shù)周 復蘇復蘇后心功能不全主要是心肌頓頓抑 最早ROSC后30分鐘內(nèi)可監(jiān)測到左室舒張末壓上升（8-10mmHg到20-22mmHg），射血分數(shù)顯著下降（55%到20%），呈現(xiàn)低心排和低血壓。 在整個個心功能障礙期間間冠脈的血流沒沒有明顯顯下降，提示是一種真種真正的心肌頓頓抑，而非持續(xù)續(xù)的心肌損傷損傷或梗死。 這種功能障礙多是暫時性的，大多可在72h完全恢
