1. Junctional escape/idiojunctional rhythm, 4 types of junctional rhythms
Junctional bradycardia, Accelerated junc-
tional rhythm, Junctional tachycardia
2. Junctional escape beat, Premature junction- types of ectopic beats in junctional rhythm
al complexes (2)
3. any rhythm that originated within the junc- what is a Junctional Rhythm
tional region (AV node or bundle of His area)
4. AV node or bundle of His what consists of the junctional region
5. 40-60bpm intrinsic rate of junctional region
6. many in Junctional Rhythms, P waves can take
one/many form(s)
7. inverted right before the QRS (seen on lead what different forms can the P wave take in
II), buried within the QRS, located just after Junctional Rhythms (3)
the QRS
8. due to retrograde depolarization of the atri- what can cause the P wave to be right after
um (AV node back towards the atria) the QRS complex in Junctional Rhythms
9. shorter (<0.12 seconds) the PR Interval, if present in Junctional
Rhythms, will be normal/shorter
10. PR interval the ______ _______ is often slurred into
the QRS complex
11. due to retrograde conduction of the atria what can cause the PR interval to be short-
(the AV node depolarizes at the same time er and slurred into the QRS complex in
the as the atrial depolarization) Junctional Rhythms

12. narrow in Junctional Rhythms the QRS complex is
normal/narrow if the ventricular system is
normal (no BBB)
13. because depolarization starts prior to the why is the QRS complex narrow in Junc-
ventricular system tional Rhythms
14. 40-60bpm Junctional Escape Rhythm (Junctional
Rhythm - JR) -- rate
15. regular Junctional Escape Rhythm (Junctional
Rhythm - JR) -- regularity
16. inverted slightly before QRS, within the QRS Junctional Escape Rhythm (Junctional
of after, or absent Rhythm - JR) -- P wave
17. narrow (unless BBB) Junctional Escape Rhythm (Junctional
Rhythm - JR) -- QRS complex
18. <0.12 seconds (shortened) OR absent Junctional Escape Rhythm (Junctional
Rhythm - JR) -- length PR interval
19. CAD, ischemia, sinus node dysfunction Junctional Escape Rhythm (Junctional
(SND), increased vagal tone Rhythm - JR) can be due to
20. idiojunctional rhythm Junctional Escape Rhythm (Junctional
Rhythm - JR) can also be called
21. <40bpm Junctional Bradycardia -- rate
22. 60-100bpm Accelerated Junctional Rhythm -- rate
23. regular Accelerated Junctional Rhythm -- regularity
24. Accelerated Junctional Rhythm -- P wave
