1、急性ST段抬高型心肌梗塞(ST-segment elevation Myocardial Infarction)急性ST段抬高型心肌梗死-STEMI 定义: 在冠状动脉病变的基础上,发生冠状动脉血供急剧减少或中断,使相应的心肌严重而持久地急性缺血坏死 It is a severe complication of atherosclerotic coronary artery disease caused by prolonged occlusion of coro...
the underpinnings of st-segment elevations in the setting of hypokalemia may be similar to those of the j-point elevation, or so-called early repolarization pattern, seen on the surface ecg of individuals in the general population. in these cases, the endocardium initiates repolarization more ...
