Junctional Escape Rhythm

Question 0

Ectopic areas

Answer 0

Ectopic = outside of where it’s supposed to be

Can create a single escape beat
Or
Set off an escape rhythm

Question 1

Junctional escape rhythm

Answer 1

Intrinsic Rate-      A)                              V) 40-60 BPM
Regularity- Regular
P Wave- Absent or inverted
P:QRS ratio- Not Applicable 
PR Interval- <o.12 sec. If present
QRS Width- normal or wide

Question 2

Junctional escape beat (JEB)

Answer 2

Looks like a sinus complex with out a P wave
SA node failed to fire
Escape comes after expected R-R interval

Question 3

Junctional rhythm

Answer 3

SA node depolarizer from JEB & doesn’t fire

SA node fails to depolarize from Dz process

Question 4

Premature Junctional Complex (PJC)

Answer 4

Occurs early in R-R interval
Absent/inverted P waves in inferior leads
Occurs early in cardiac cycle
No P wave found = not a PAC

Question 5

Accelerated Junctional Rhythm

Answer 5

Intrinsic Rate-      A)                              V) 60-100 BPM
Regularity- Regular 
P Wave- Absent or Inverted
P:QRS ratio- Not applicable 
PR Interval- <o.12 sec. If present 
QRS Width- Normal or wide

Question 6

Junctional Tachycardia

Answer 6

Intrinsic Rate-      A)                              V) >100 BPM
Regularity- Regular 
P Wave- Absent or inverted 
P:QRS ratio- Not applicable 
PR Interval- <0.12 sec if present 
QRS Width- Normal or wide

Question 7

Reentry Circuit Criteria

Answer 7

1) 2 separate path ways
2) pathways are different properties
3) one path way slows down

Question 8

Pseudo S wave

Answer 8

Buried P wave usually in S wave

Question 9

AV Nodal Reentry Tachycardia

Answer 9

Intrinsic Rate-      A)          V) 140-250 BPM (commonly 170-250 BPM)
Regularity- Regular 
P Wave- Absent or inverted 
P:QRS ratio- 1:1 if P waves are present 
PR Interval- None or R-P interval 
QRS Width- Normal or wide

Question 10

WPW Wolf Parkinson White= Delta wave

Answer 10

Delta wave only in AV Reentry tachycardia
