 Myocardial stunning

In cardiology, stunned myocardium is a state when some section of the myocardium (corresponding to area of a major coronary occlusion) shows a form of contractile abnormality.This is a segmental dysfunction which persists for a variable period of time, about two weeks, even after ischemia has been relieved (by for instance angioplasty or coronary artery bypass surgery).
