2 SA nodes has anybody had the same?

[flathead378]

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?

I was diagnosed with dual SA nodes after 3 episodes of my heart rate going up to 228.  They went up through my groin and eliminated one of them. That was when I was 35. I am now 52 & am experiencing the same fluttering feeling in my chest, although I haven't experienced prolonged a rapid heartbeat. I was wondering if the second node could grow back. I don't currently have insurance, so I have no way of checking. Does anyone know if that's possible?

I'll take a try at this.... First, is it possible that you are mixing up SA Node and AV Node?  The term "dual AV nodal pathways" is loosely used when analyzing ECG and telemetry strips.  This term might suggest two, distinct anatomic structures related to the atrioventricular (AV) node, but often the true understanding of this entity is either missing or incomplete.   Dual AV nodal pathways have been shown to be responsible for many arrhythmias, most notably AV nodal reentrant tachycardia.  AVNRT is caused by a reentry circuit in or around the AV node.The circuit is formed by the creation of two pathways forming the re-entrant circuit.  These are referred to as slow and fast pathways.  These paths are form of tissue very similar to that of the AV node, and some physicians even consider them as part of the AV node.  The slow path is the one usually targeted for ablation.  AVNRT is a very common form of SVT, favoring females to males.

I have been told i have two sinoatrial nodes as well. It came as quite a shock to me when i was in the ER for my syncope that they took an ekg and found evidence of it.  Dont feel alone.  Apparantly its a common thing.  I have just been sent to a cardiologist and they said they are going to put a catheter up my arm and burn the extra node off.  I know there are lots of procedures so i would check out a good cardiologist or three and weigh your options

Hey there James,

i found out the other day that I have two sinoatrial nodes one 400 milliseconds behind and the other kicking in when im exercising or doing anything strenuous.

The cardiologist said not to worry about it but to come back in 6 months to check it again in case theyre wrong.

Interesting huh?!?

Im 42.

I myself have two SA Node and a Dual AV node. I had ablation done and is currently on 200mg - 300mg of beta blocker daily to control HR / SVT. It a bit concerning and at times; I am awaken during the night with irregular HR or experience syncope without warning at any given time. Yet I have a normal / healthy heart according to my cardiac stress test. Ever heard of two SA node & a Dual AV node??

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

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.

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.

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.
