AV Junctional Rhythm And Complexes

Question 1

AV junctional escape rhythm?

Answer 1

An AV junctional rhythm that emerges as a result of a failure of conduction or slowing of a normally faster physiologic pacemaker.

Question 2

AV junctional rhythm, accelerated?

Answer 2

An AV junctional rhythm that is more rapid (generally between 70-130bpm) than the usual rate of of the AV junction
It is secondary to enhanced automaticity of the AV junction and lacks an paroxysmal onset and termination.

Question 3

AV junctional escape complexes?

Answer 3

Isolated AV junctional complexes that emerge as a result of the failure of conduction or slowing of a normally faster physiologic pacemaker.

Question 4

AV junctional premature complexes?

Answer 4

Isolated AV junctional complexes that occur prematurely relative to the basic sinus cycle.

Question 5

AV junctional rhythm?

Answer 5

A regular rhythm characteristically at a rate of 35-60bpm that originate in the AV junction, with an inverted retrograde P waves in lead II, III and aVF.
The P wave may occur prior to or within or after the QRS complex.
in the absence of retrograde block, the PRi is less than 0.12 sec.
