stunned my·o·car·di·um

impaired myocardial contractile performance following a period of ischemia and ultimately reversible.

stunned myocardium

a condition of impaired myocardial contractile function, cellular biochemical characteristics, and microvasculature function in the absence of gross myocardial necrosis. It can last for minutes to days and is caused by ischemia that is either brief or occurs in the area immediately outside an infarct zone.

'stunned' myocardium

Transient–hrs to days in duration postischemic contraction defects that follow myocardial reperfusion in acute MI. Cf Hibernating myocardium.
