Abbreviation:<unk> 
RV infarction accompanies ~25% of inferior<unk> s
Hemodynamically significant only 10% of the time
Do NOT reduce preload (caution with NTG)
Optimise preload (ensure volume replete)
Posterior (aka inferolateral) infarction is rarely isolated (~3-8% of all AMIs)
Treat as<unk> 
Look for reciprocal changes, except in aVR and V1
Apply V7, V8, V9 leads and repeat ECG looking for ST elevation
Usually will see changes in V6 OR II, III, aVF

The new title, “Non-ST-Elevation Acute Coronary Syndromes,” emphasizes the continuum between UA and<unk> <unk>  myocardium is damaged enough to increase biomarkers, UA is not.
Any of the following:
1 mm of ST elevation in any two contiguous leads except V2 and V3.
The acceptable degree of ST elevation in V2 and V3 changes based on age and gender.
In women: 1.5mm elevation in V2 and V3
In men under 40: 2.5mm elevation in V2 and V3
In men 40 and older: 2mm elevation in V2 and V3
The acceptable degree of ST elevation in V2 and V3 changes based on age and gender.
Q waves in V1-V3 over time
STD inf leads
STD in aVL (most common lead to see reciprocal change)
STE V1 (only lead looking at RV)
<unk> II > II (III more R facing)

STE V1 > V2, STE V1 + STD V2
STD in V1, V2, V3; 
R>S in V1 
Tall R waves in V1-V3 (Q waves on back of heart) w/ upright TWs
Doesn't apply in SVT
Hyperoxia may increase<unk>  injury
Avoid supplemental oxygen unless hypoxic
Activate cath lab for patients with<unk>  on prehospital ECG even if ST elevation has resolved by time of arrival at hospital 
Avoid supplemental oxygen unless hypoxic

>6mm limb leads
>10mm precordial leads

0.1mV in two or more contiguous leads
ST-segment elevation myocardial infarction
Cardiac
Non-ST-elevation myocardial infarction
ST-segment elevation myocardial infarction 
Unstable angina
Post-MI 
Acute coronary syndrome 
Previous MI with recurrent ischemia in same area
