Dual AV node pathways and AVNRT

Some individuals have dual AV node pathways (up to 20% of individuals). Normally, conduction spreads through the fast pathway and gets blocked in the slow pathway. However, after a PAC, the electrical activity cannot spread through the fast pathway (which is still in a refractory period), but can get conducted through the slow pathway which then conducts both down to the ventricle and up to the atrium, through the recovered “fast pathway”, thus creating a tachycardia with retrograde P waves

AVRT (after PAC or PVC)

Accessory

pathway

Similar process happens in case of accessory pathway that is conducting retrogradely. We have 2 pathways that create a reentrant circuit after a PAC or PVC.


Arrows point to the retrograde P that is superimposed on ST segment and looks as a notch on ST segment

Retrograde P wave

Pseudo-r’ in V1 + Pseudo S in inf leads


ECG of the previous pt in sinus rhythm after adenosine. Note the difference (no “pseudo-r’ “ or “pseudo S”)


QRS width the difference (no “pseudo-r’ “ or “pseudo S”)

Narrow complex

Regular or regularly irregular

Look for P waves

Assess RP interval

Sawtooth P,

esp. rate~150

-Atrial flutter

Short RP (<1/2 RR)

-AVNRT

-AVRT

-Atrial tachycardia

Long RP (>1/2 RR)

-Atrial tachycardia

-Atypical AVNRT
