ST segment depression, chest pain, hypotension, or significant arrhythmia
How does a right ventricular infarct present?
inferior ECG changes, hypotension, JVD, hepatomegaly, and clear lungs
ECG progression of MI
Peaked T waves - ST elevation - Q waves

T wave inversion is sensitive but not specific.
Which 3 agents have been shown to reduce mortality in MI?
aspirin, Beta blockers, ACE inhibitors
What are the anterior leads?
What are the lateral leads?
aVL, I
What are the Inferior leads?
II, III, and aVF
Where does a posterior infarct show up on ECG?
Large R wave in V1 and V2,
ST depression in V1 and V2,
Prominent T waves in V1 and V2
Which patients with chest pain should receive heparin?
all patients with MI - prevents progression of thrombosus, no mortality benefit

3-8 hours
CK-MB peaks at 24 hours, Troponin peaks at 48 hours and stays elevated for 6 days

within 10 days
When is papillary muscle rupture most likely to occur after MI?
2-10 days
What is the difference between ventricular pseudoaneurysm and ventricular aneurysm?
pseudoaneurysm - myocardial rupture is contained by pericardium, surgical emergency, often rupture

ventricular aneurysm - rarely ruptures, higher incidence of VTach
What is Dressler's syndrome and when is it most likely to occur?
fever, malaise, pericarditis, leukocytosis, and pleuritis - occurs weeks to months after an MI
