床边诊断可以早期发现和及时处理急性心肌梗塞所致的心律失常,从而使其住院死亡率下降由30％降至15％。当前有条件的冠心病监护室其死亡率几乎完全是由于机械性的合并症,来自心脏机械性损害。其中最常见的是泵衰竭,这种合并症最少有1/3～1/2的心肌梗塞病人发生。急性心肌梗塞时造成心脏功能损害主要是通过降低收缩力、产生室壁运动异常和改变心肌的顺应性。前壁心
Bedside diagnosis of early detection and timely treatment of arrhythmias caused by acute myocardial infarction, resulting in a decrease in hospital mortality from 30% to 15%. The current conditional CHD mortality is almost entirely due to mechanical complications resulting from mechanical heart damage. The most common of these is pump failure, with at least one-third to one-second myocardial infarction in this comorbid condition. Cardiac dysfunction caused by acute myocardial infarction is mainly through the reduction of contractility, wall abnormalities and changes in myocardial compliance. Front heart
