Q

atrial flutter is called a ___ rhythm (think rate)

A

regular

28
Q

run of repeated premature beats is initiated and is usually a PAC

A

PSVT

29
Q

psvt can be caused by

5

A
  1. overexertion
  2. emotional stress
  3. stimulants (e.g. drinking a lot of red bulls and caffeine
  4. digitalis toxicity
  5. CAD
30
Q

atrial flutter - risk for

A

stroke because of risk of thrombus formation in atria

31
Q

may use ___ to convert flutter to sinus

A

amiodarone

32
Q

how do we know psvt is above ventricles

A

because qrs is normal (under three boxes)

33
Q

occurs with exercise, hypotension, hypovolemia, myocardial ischemia, CHF

A

sinus tachy

34
Q

psvt treatment goal

A

stop heart rate so SA node can take over, other times you may need to cardiovert

35
Q

PSVT - ok or fix?

A

we want to fix this rhythm

36
Q

qrs, to be normal should be less than?

A
37
Q

Does PSVT originate from ventricles

A

no

38
Q

atrial tachyarrhythmia identified by recurring, regular, sawtooth-shaped flutter waves

A

atrial flutter

39
Q

why is atrial flutter called a regular rhythm

A

because ventricular response is regular

40
Q

psvt aka

A

“narrow complex tachycardia”; we know it’s above the ventricles, so it’s something to do with the atrias

41
Q

PSVT originates in

A

ectopic focus anywhere above bifurcation of Bundle of His

42
Q

atrial flutter significance

A

high ventricular rates with atrial flutter can decrease CO and cause serious consequences such as HF

43
Q

psvt - if pt becomes hemodynamically unstable, what may be used

A

DC cardioversion

44
Q

risk for stroke because of blood sitting in atrium

A

flutter

45
Q

occurs with CAD, pulmonary emoblus, chronic lung disease, cardiomyopathy

A

atrial flutter

46
Q

paroxysmal refers to

A

an abrupt onset and termination

47
Q

what is used for atrial flutter lasting > 48 hours

A

coumadin

48
Q

atrial flutter usually occurs with

5

A
  1. CAD
  2. mitral valve disorders
  3. pulmonary embolus
  4. chronic lung disease
  5. cardiomyopathy
49
Q

paroxysmal refers to

A

an abrupt onset and termination

50
Q

psvt dx of choice

A

adenosine (brings hr down)

51
Q

psvt - what can cause hemodynamic collapse in WPW syndrome

2

A
  1. digitalis

2. CCBs

52
Q

atrial flutter curative therapy

A

radiofrequency catheter ablation

53
Q

PSVT originates in

A

ectopic focus anywhere above bifurcation of Bundle of His

54
Q

psvt tx - first do what, and then

A

first do vagal maneuvers, if they don’t work give meds

55
Q

psvt treatment include

2

A
  1. vagal stimulation

2. drug therapy

56
Q

radiofrequency catheter ablation of accessory pathways; kills certain parts of heart that cause these abnormal tachys is to

A

psvt

57
Q

what may be used to convert atrial flutter to sinus rhythm in emergency

A

electrical cardioversion

58
Q

PSVT is a ____ syndrome (think rate)

A

tachy

59
Q

PSVT are usually what but are hard to tell why

A

usually PACs but hard to tell because it’s too fast

60
Q

psvt signifiance

A

prolonged episode of HR >180 may precipitate decreased CO with hypotension and myocardial ischemia

61
Q

radiofrequency catheter ablation of accessory pathways; kills certain parts of heart that cause these abnormal tachys is to

A

psvt

62
Q

occurs with overexertion, emotional stress, stimulants, CAD

A

psvt

63
Q

psvt can be caused by

5

A
  1. overexertion
  2. emotional stress
  3. stimulants (e.g. drinking a lot of red bulls and caffeine
  4. digitalis toxicity
  5. CAD
64
Q

atrial flutter tx primary goal is to

A

slow ventricular response by increasing AV block

65
Q

PSVT - ok or fix?

A

we want to fix this rhythm

66
Q

PSVT are usually what but are hard to tell why

A

usually PACs but hard to tell because it’s too fast
