Q

What does not decrease mortality with MI tx?

A

m.o.n

18
Q

Do you need CK-MB/troponins to dx a STEMI?

A

No, its a STEMI

19
Q

Tell me the leads affected with inferior wall MI?
The leads for lateral MI?
the leads for anterior MI?
The posterior wall MI?

A

2,3,avf
1, AVL, V4, V5, V6
V2-V4
V1-V2, ST-segment depression

20
Q

difference between RBBB, LBBB.

A

LBBB assoc with ischemia

RBBB no big deal

21
Q

Post MI care? (a,b,c,d,e)

A

aspirin, betblockers, cholesterol, DM, exercise

22
Q

MCC of abnormal AV conduction of heart?

A

ischemia

23
Q

what do you do for symptomatic 3rd degree av block?

what do you give for asymptomatic 3rd degree av block?

A

atropine (1st)

pacemaker (2nd)

24
Q

whats dressler syn?

A

post MI the dead heart muscle gives off antigens and an immune response is initiated=pericarditis

25
Q

how do you tell the difference between valve rupture and septal rupture?

A

septal rupture has an increase in saturation from RA to RV.

26
Q

Inferior wall MI associated with?
best initial test?
best therapy?

A

right vent=hypotension
right vent chest leads
IV fluids

27
Q

most sensitive test for prinzmetal angina

A

angiogram

28
Q

how do you differentiate prinzmetal from unstable?

A

stress test, angiogram are normal with prinzmetals

29
Q

Definative dx for prinzmetal?

tx?

A

ergonovine during angiography

CCB

30

which is chronic

A

dobutamine

digoxin.

35
Q

how do you tell if the pt is in systolic or diastolic heart failure?
whats the difference in management?

ACE!

39

in diastolie

ischemia
