透壁性下后壁心肌梗塞常合并右心室 (RV)梗塞,尽管左心室(LV)功能完好仍能造成血流动力学损害。RV 梗塞时血流动力学恶化的程度与 RV 游离壁功能丧失的程度有关,但有些病人能耐受 RV 收缩力严重抑制而无血流动力学损害,另一些病人则虽然 RV 损伤程度相似却发生心输出量(CO)下降。本文旨在研究严重 RV 梗塞的病人其 RV 功能与血流动力学损伤程度的决定 Transmural wall posterior wall myocardial infarction often associated with right ventricular (RV) infarction, although left ventricular (LV) intact still can cause hemodynamic damage. The extent of hemodynamic deterioration of RV infarction is related to the extent of loss of RV free wall function, but some patients are highly resistant to RV contractility without hemodynamic damage, whereas others experience RV injury similar in magnitude. Cardiac output (CO) decreased. This article aims to study the severity of RV function and hemodynamic damage in patients with severe RV infarction
