Cerebral lesions may contribute to a transient left ventricular ballooning syndrome that can mimic acute myocardial infarction. Fibrinolytic therapy or GP IIb/IIIa antagonists should be withheld in cases of neurologic disorder or unconsciousness even in the presence of ST-elevation.ECG transmission by telemetry and myocardial infarction alarm networks allow correct diagnosis and catheter treatment within required time limits.
