Q

3 causes of a flutter

A

ischemia

cardiomyopathy

dig toxicity

33
Q

mc type of aflutter

34
Q

macro reentry

A

a flutter w. consistent block

35
Q

how do you differentiate a.flutter from AVNRT

A

a flutter is slower than AVNRT

~150

36
Q

tx for a flutter w. consistent block

A

vagal maneuver

adenosine → unmasks flutter

37
Q

tx for stable afib

A

rate control: AVNB

if hypotensive: shock at 200 joules PLUS heparin

CHADS score

38
Q

tx for unstable afib

A

shock first

THEN

amiodarone

39
Q

is rate control or rhythm control preferred in afib tx

A

rate → AVNB drugs

40
Q

nl for QRS for peds pt

A

< 0.08 sec

41
Q

a fast and wide rhythm is __ until proven otherwise

42
Q

rate in v tach

43
Q

indication for sustained v tach

A

lasts > 30 sec

44
Q

tx for stable vtach

A

amiodarone

THEN

cardioversion

45
Q

tx for unstable v tach

A

shock w. 200 joules of electricity

46
Q

tx for torsades

47
Q

basically the treatment for wide QRS is

A

when in doubt, shock it out

48
Q

pre shock tx (3)

A

sedate

ketamine

propofol

49
Q

wide and irregular =

A

afib w. blocks (abberency)

50
Q

fx for v fib

A

chest compressions early

then shock until rhythm is established

51
Q

meds to try for fib

A

epi

vasopressin

amiodarone

Mg

52
Q

which AVNB are concerning

A

mobitz II

third degree

53
Q

tx for mobitz II and third degree blocks

A

card consult

unstable: transcutaneous pacing
meds: epi, atropine, dopamine

54
Q

3 causes of brady arrhythmias

A

lytes

ischemia

drugs

55
Q

are brady arrhythmias usually responsive to atropine

56
Q
A

afib

fast, narrow, irregular

58
Q
A

sinus tachy

59
Q
60
Q
61
Q
A

vtach

p waves present → NOT SVT

62
Q
A

AVRT

rate: >200

pathologic

consider WPW

63
Q
A

aflutter 3:1

64
Q
A

AVNRT vs Aflutter 2:1

clue: rate 150 → too slow to be AVRT

??? what?!
