Time to fibrinolysis

What It Means
The median time from arrival to administration of fibrinolytic agent in patients with ST segment elevation or left bundle branch block (LBBB) on the electrocardiogram (ECG) performed closest to hospital arrival time.

Why It Is Important
Clinical evidence shows that AMI patients with these particular symptoms are at a high risk of death. Fibrinolysis can significantly reduce that risk if it is done in a timely manner.
