Had frequent 160 bpm avnrt which was recently ablated & it has given me my life back. I’m 78 😮. I didn’t much fancy a catheter through my groin so I stupidly delayed treatment. All I can say is, get it done.
Do premature beats only/always take the slow path? Or is it that premature beats hop onto the slow pathway as it's the only one available at the time??
Please note that the fast and slow pathways are NOT intranodal as this person explains. They are extranodal and consist of the fast and slow pathway approaches to the compact AV node. This anatomic arrangement has been known since early 90's
Can someone plzz explain if the normal pathway is the fast one then how is there a nodal delay.... Nodal delay term suggests that it should b a slower pathway rgt Any explanation is appreciated
i think what akhil raj is saying is that when impulse reaches to the av node from atria , there is still the lingering action of refractory period of the previous impulse . hence the delay
Simpy put... the impuse travels very fast through the FP....but because of the long refractory period....total time to the next impulse being conducted is delayed.. hence the slowing produced by the AV node

By far the best video on AVNRT. Thank you
The clearest explanation of AVNRT I've seen. Ever! Thank you! Nice anthropomorphization of our little impulse too! 😁
Thank you! Watched many AVNRT videos. This is truly clear cut!

Could you elaborate?
So in other words INTER-nodal?
Can you please explain the mechanism of fast slow and slow-slow AVNRT also?
So the ventricles in the second case get their signal only from the accessory pathway?

Any explanation is appreciated
fast pathway has longer refractory period :D
