25
fx for fast, narrow rhythm in stable pt
try vagal adenosine AVNB drugs
26
what drug is used for rhythm control
adenosine
27
what drugs are used for rate control
AVNB → amiodarone, bb, ccb, dig
28
pt ed for adenosine
they will feel flushed and anxious
29
narrow + irregular rhythm makes you think of
afib aflutter w. variable block
30
afib is usually seen w. what conditions
COPD HTN ischemia etoh PE thyroidtoxicosis
31
HR w. a flutter
\>150
32
3 causes of a flutter
ischemia cardiomyopathy dig toxicity
33
mc type of aflutter
2:1 block
34
macro reentry
a flutter w. consistent block
35
how do you differentiate a.flutter from AVNRT
a flutter is slower than AVNRT ~150
36
tx for a flutter w. consistent block
vagal maneuver adenosine → unmasks flutter
37
tx for stable afib
**rate control:** AVNB if hypotensive: shock at 200 joules PLUS heparin CHADS score
38
tx for unstable afib
shock first THEN amiodarone
39
is rate control or rhythm control preferred in afib tx
rate → AVNB drugs
40
nl for QRS for peds pt
\< 0.08 sec
41
a fast and wide rhythm is __ until proven otherwise
v tach
42
rate in v tach
150-200
43
indication for sustained v tach
lasts \> 30 sec
44
tx for stable vtach
amiodarone THEN cardioversion
45
tx for unstable v tach
shock w. 200 joules of electricity
46
tx for torsades
Mg
47
basically the treatment for wide QRS is
when in doubt, shock it out
48
pre shock tx (3)
sedate ketamine propofol
49
wide and irregular =
afib w. blocks (abberency)
50
fx for v fib
chest compressions early then shock until rhythm is established
51
meds to try for fib
epi vasopressin amiodarone Mg
52
which AVNB are concerning
mobitz II third degree
53
tx for mobitz II and third degree blocks
card consult unstable: transcutaneous pacing meds: epi, atropine, dopamine
54
3 causes of brady arrhythmias
lytes ischemia drugs
55
are brady arrhythmias usually responsive to atropine
no
56
afib fast, narrow, irregular
57
SVT
58
sinus tachy
59
v tach
60
vtach
61
vtach p waves present → NOT SVT
62
AVRT rate: \>200 pathologic *consider WPW*
63
aflutter 3:1
64
AVNRT vs Aflutter 2:1 clue: rate 150 → too slow to be AVRT ??? what?!
65
flutter 2:1
66
AVNRT
67
SVT
68
**WPW** short PR delta wave
69
**WPW** short PR delta wave
70
AVRT rate: 225
71
AVRT rate 220
72
afib
73
afib
74
no atrial activity
75
vtach
76
vtach
77
afib w. avrt antidromic
78
third degree AV block
