-T wave inversion/S-T elevation
>continuous telemetry monitoring
>Hx
>lab studies
-cardiac markers
<CK, CK isoenzymes, Troponin
-electrolytes, basic or complete
-clotting studies
-CBC
>echocardiogram

>Hx
What is the EKG reading of and MI? ✅>ST elevation in leads determine location of MI
>T wave may be inverted
>Development of Q wave - permanent when it develops
-Diagnosis
<Unstable angina: clinical evidence but no evidence on EKG or cardiac biomarkers
<STEMI: EKG evidence of MI with changes in 2 contiguous leads; significant damage
to myocardium
<NSTEMI: elevated cardiac biomarkers (troponin) but no definite EKG evidence of
acute MI
-Recovery: ST segment returns to normal.
What labs do you gather for a supposed MI? ✅>Troponin=elevated
>Cretine Kinase and Isoenzymes
-increased within hrs./peaks @ 24
>Myoglobin
-increase in 1-3 hrs/peaks @ 12
-(-) results can rule out MI
