Ross - Don't LoOse Your Lunch" Flashcards
this is a mess, i did my best
my jaynstein deck is much better and has all the EKG pictures
2 indications for unstable pt
CP
SOB
how to determine stable vs unstable pt
vitals → esp hypotn
e.o hyperperfusion → appearance, AMS, CP, dyspnea
PMH
on an ekg, 6 seconds =
30 boxes
when is unsynchronized cardioversion used
pulseless pt
vtach, vfib
5 common tachycardias
sinus tachy
afib
a flutter
SVT
v tach
narrow + regular rhythm makes you think of
sinus tachy
SVT/PSVT
types of SVT
AVNRT (AV node reentrant tachy)
AVRT (AV reciprocating reentrant tachy)
3 causes of v tach
ischemia
lyte disturbance
toxicity
AVRT is caused by
reciprocating reentrant tachy
HR in AVRT is
>200
what pt makes you think of AVRT
young pt w. HR > 200
what is an orthodromic p wave
retrograde → after QRS
what is antidromic p wave
wide QRS + tachy
in regards to the p wave, most WPW rhythms are
orthodromic
what do you think when you see AVRT w. a delta wave
WPW
very pathologic
tx for AVRT
AVNB drugs
tx for AVRT w. WPW
procainamide
OR
shock
what pt makes you think of AVNRT
healthy young women
AVNRT is caused by
circular movement w.in AV node
causes of AVNRT
etoh
caffeine
stimulants
HR in AVNRT
180-200
is AVNRT pathologic
not usually
tx for any fast, narrow rhythm in an unstable pt
shock w. 50-100 joules
fx for fast, narrow rhythm in stable pt
try vagal
adenosine
AVNB drugs
what drug is used for rhythm control
adenosine
what drugs are used for rate control
AVNB → amiodarone, bb, ccb, dig
pt ed for adenosine
they will feel flushed and anxious
narrow + irregular rhythm makes you think of
afib
aflutter w. variable block
afib is usually seen w. what conditions
COPD
HTN
ischemia
etoh
PE
thyroidtoxicosis
HR w. a flutter
>150
