Cardio Flashcards
(43 cards)
What 2 EKG findings suggest STEMI?
- ST segment elevation
- new LBBB
If patient can’t walk for stress test, what 2 meds can administer for pharmocologic stress?
- dobutamine
- adenosine
What is acute treatment for ACS?
- Morphine (prn)
- O2 (prn)
- Nitrate
- ASA
- BB
- ACEI
- Statin
- Heparin/Clopidogrel
What is purpose of administering BB for ACS?
- reduce myocardial work
- prevent ventricular arrthythmia
What are the indications for thrombolysis in ACS?
- can’t catheterization (PCI facility is >60min away)
- in acute disease (STEMI)
- within 12hr of onset
STEMI –> within how long need cath?
90min
valsalva does what?
decrease venous return (decrease preload)
when use synchronized cardioversion?
unstable Afib/flutter/SVT
when use unsynchronized cardioversion?
no coordinated cardiac electrical activity –> V tach/fib
arrhythmia –> QRS fast & wide –> what drug for tx?
amiodarone
arrhythmia –> QRS fast & narrow –> what drug for tx?
adenosine
arrhythmia –> QRS slow –> what drug for tx?
atropine
Afib/flutter –> what drug for tx?
- BB
- CCB: verapamil, diltiazem
no pulse –> ACLS –> what rhythms do you shock, and which rhythms don’t shock?
VT/VF: shock
PEA/asystole: no shock
VT/VF –> ACLS –> what drugs for tx?
epi
amio
epi
PEA/asystole –> ACLS –> what drugs for tx?
epi
0
epi
Afib –> >48hr –> want to cardiovert –> need to be on warfarin for how long before cardioversion?
3-4 wks
Afib –> >48hr –> why need to be on warfarin for 3-4wks before cardioversion?
to prevent embolization of mural thrombus
Afib –> <48hr –> want to cardiovert –> when can cardiovert?
right away if necessary
aortic regurg –> murmur?
blowing diastolic murmur at L sternal border +/- mid-diastolic rumble (Austin-Flint murmur)
acute pericarditis –> possible etiologies (6)
- viral infection
- TB
- SLE
- uremia
- drugs
- neoplasm
acute pericarditis –> first line tx
NSAID and ASA
PE –> EKG finding
S1Q3T3 (right heart strain)
HOCM –> murmur decreases or increases with valsalva?
increases
