Suffering From Atrial Fibrillation. Unable To Treat With Medicine. Ablation Done. History Of Tachycardia. Repeat EP Study Required?
Hello, I m a 37 y/o male with hx of AV Nodal reentrant tachycardia s/p ablation in 2003. When I presented to ER in 03 I was in A. Fib. I was recently in ER with another episode of A.Fib, and they were unable to convert me with medication . Do you think another abnormal pathway is the most likey cause, and a repeat EP study would make sense? Thank you!

Hello
As you have said that you have AVNRT , ablation in 2003 , again having A-fib , chemical cardioversion was unsuccessful
The next step would be DC cardioversion after 4-6 weeks with EP studies to be done again to check for any residual pathway.
It is not possible that a single readiofrequency ablation can solve the problem completely.
You need to start on high dose beta blockers + calcium channel blockers.
Pathways between atria and ventricles are usually more than what we see on EP studies , but a review by EP speciailist after cardioversion would be best plan of action
Hope this helps
Take care
