Q

What 2 EKG findings suggest STEMI?

A
  • ST segment elevation

- new LBBB

2
Q

If patient can’t walk for stress test, what 2 meds can administer for pharmocologic stress?

A
  • dobutamine

- adenosine

3
Q

What is acute treatment for ACS?

A
  • Morphine (prn)
  • O2 (prn)
  • Nitrate
  • ASA
  • BB
  • ACEI
  • Statin
  • Heparin/Clopidogrel
4
Q

What is purpose of administering BB for ACS?

A
  • reduce myocardial work

- prevent ventricular arrthythmia

5
Q

What are the indications for thrombolysis in ACS?

A
  • can’t catheterization (PCI facility is >60min away)
  • in acute disease (STEMI)
  • within 12hr of onset
6
Q

STEMI –> within how long need cath?

A

90min

7
Q

valsalva does what?

A

decrease venous return (decrease preload)

8
Q

when use synchronized cardioversion?

A

unstable Afib/flutter/SVT

9
Q

when use unsynchronized cardioversion?

A

no coordinated cardiac electrical activity –> V tach/fib

10
Q

arrhythmia –> QRS fast & wide –> what drug for tx?

A

amiodarone

11
Q

arrhythmia –> QRS fast & narrow –> what drug for tx?

A

adenosine

12
Q

arrhythmia –> QRS slow –> what drug for tx?

A

atropine

13
Q

Afib/flutter –> what drug for tx?

A
  • BB

- CCB: verapamil, diltiazem

14
Q

no pulse –> ACLS –> what rhythms do you shock, and which rhythms don’t shock?

A

VT/VF: shock

PEA/asystole: no shock

15
Q

VT/VF –> ACLS –> what drugs for tx?

A

epi

amio

epi

16
Q

PEA/asystole –> ACLS –> what drugs for tx?

A

epi

0

epi

17
Q

Afib –> >48hr –> want to cardiovert –> need to be on warfarin for how long before cardioversion?

A

3-4 wks

18
Q

Afib –> >48hr –> why need to be on warfarin for 3-4wks before cardioversion?

A

to prevent embolization of mural thrombus

19
Q

Afib –> <48hr –> want to cardiovert –> when can cardiovert?

A

right away if necessary

20
Q

aortic regurg –> murmur?

A

blowing diastolic murmur at L sternal border +/- mid-diastolic rumble (Austin-Flint murmur)

21
Q

acute pericarditis –> possible etiologies (6)

A
  • viral infection
  • TB
  • SLE
  • uremia
  • drugs
  • neoplasm
22
Q

acute pericarditis –> first line tx

A

NSAID and ASA

23
Q

PE –> EKG finding

A

S1Q3T3 (right heart strain)

24
Q

HOCM –> murmur decreases or increases with valsalva?

A

increases

25
Q

HOCM –> what tx decreases intensity of murmur?

A

BB –> increase preload

26
Q

what is Eisenmenger’s synd?

A

ASD/VSD/PDA –> reverse from LtoR shunt to RtoL shunt –> cyanosis

27
Q

b/l renal artery stenosis –> what med is contraindicated? why?

A

ACEI –> decrease renal perfusion and GFR –> accelerate renal failure

28
Q

16M –> no PMHx, no meds –> no complaints –> routine EKG shows short PR, slurred QRS

what condition?

A

wolff-parkinson-white synd

29
Q

wolff-parkinson-white synd –> pathophys

A

anomalous embryonic development of myocardial tissue –> fibrous tissue bridge bw atria & ventricle –> accessory pathway

30
Q

WPW synd –> EKG findings

A
  • shortened PR
  • delta wave
  • wide, slurred QRS
31
Q

WPW synd –> COD

A

rapid conduction thru accessory pathway –> unstable ventricular rate –> cardiac output decrease –> sudden cardiac death

32
Q

BB toxicity –> tx

A

glucagon –> increase cardiac contractility, HR, conduction

33
Q

who gets AAA screening?

A

65-75M who have ever smoked

34
Q

alcohol abuse –> dilated cardiomyopathy –> tx? why?

A

stop alcohol use –> almost completely reversible

35
Q

differentiate: dressler’s synd vs post-infarction pericarditis

A
