|
Loud S1
|
|
|
What four things cause a stress test to be considered positive?
|
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. |
|

|
aspirin, Beta blockers, ACE inhibitors
|
|
|
What are the anterior leads?

V1-V4
|
|
|
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
|
|
|
How early do CK-MB and troponin rise? When do they peak?
|
3-8 hours
CK-MB peaks at 24 hours, Troponin peaks at 48 hours and stays elevated for 6 days |
|
|
Which arrhythmia is a poor prognostic indicator in the setting of anterior MI?
|
second degree and third degree heart block
|
|
|

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
