2 SA nodes has anybody had the same?

I have had PSVT for 7 years now and have had 4 heart ablations with no luck,  after the first ablation my heart rate would not drop below 280 so they stoped my heart in hope it would re-boot in a sence and go back to normal, it did but they still could not figure out why I was having severe SVT.  so i had another ablation and another and another, and now we have figured out during my last ablation that I have 2 SA nodes and hundreds of SV nodes and they keep growing back. I have had no luck with my Docs being able to remove the 2nd SA node its too far over on the left atrium.

Has anyone had the same issue with the SV nodes growing back so fast and has anyone had the issue with having 2 SA nodes on seperate sides of the heart?

Sorry to read you have such a problem with node regeneration, I have not read of it here before.  You may want to add your post the the heart disease community too

At you young age I would think every effort should be made to get you back in NSR, seems much has already been tried.  I could be that you will have to have your nodes shut down (yes I did read about the regeneration) and have a pacemaker regulate your heart rate.

Perhaps you have the info a bit off. I've not read of a duality of the SA node and I think you mean AV (atrioventricular) rather than SV (sinoventricular). I doubt there could be hundreds of these nodes (especially the AV) but I think what you have are areas of tissue that are capable of firing off a beat. These ectopic beats sometimes take over and create what is called junctionaly rhythm. In fact, all myocardial tissue is capable of generating electrical impulses (a normal heart has a concentrated area of polarization, the SA node, which dominates). It's a grand design wherin if your SA node fails, a 'rescue' beat is shot off to keep you going. Many people live in constant junctional rhythm.

The entire heart muscle is capable of producing a beat.

I really hope you've found a solution and that they've been able to calm things down for you and your ticker.

Best wishes.

I was born with 2 SA nodes - when I was born my heart rate would go up to 280 beats if anyone even touched me. I went to Sick Kids hospital in Toronto and they used amiodarone w- which was in trial at the time to knock the other SA node out. I have not had any serious problems since
