Troponin I

The gold standard and most specific lab test for an MI


the fastest lab test for an MI

Doubles, 2h

If myoglobin ______ in _________ it is a good indication an MI has occured


ST elevation indicates

Unstable angina or Non STEMI

ST depressions indicates

> 1mm, 2 buddy leads

In order for ST elevation to be "significant" it must be ______ and in _________

Ischemic, injured

_____ and _______ tissue can be saved


Cannot be saved

tall or inverted T wave

Ischemia is indicated by a _________


Injury is indicated by ST segment __________

Infarction (Acute)

is indicated by an abnormal Q wave, possible ST seg elevation, and possible t wave inversion

Infarction (Age unknown)

is indicated by an abnormal Q wave where the ST seg and T wave have returned to normal

30 min

door to drug time for fibrinolytic therapy is
