Pacemaker node
Common Questions and Answers about Pacemaker node
pacemaker
Never heard of an AV node recovering. Usually when done deliberately, a pacemaker is installed. Perhaps they just got a bit too close and stunned it. That happens with ablations some times, an area is just bruised, not fully ablated and the arrhythmia will come back. Only your EP knows for sure how much damage was done.
How are you feeling now? Sluggish? How's the heart rate?
In 2013 I had an AV Node ablation. I am pacer dependent. In 2015 my pacemaker was upgraded to a Bi-V due to "pacemaker syndrome".
Since that time I have periods of extremely irregular heartbeats. These can last up to 8 hours. Various medical professionals have checked my pulse during these periods and confirm what I already knew.
I do not understand why the pacemaker does not prevent these periods of IHB.
Hi, May be unrelated but my Mom had uncontrolled arrhythmia with many things tried to control it. Finally an av node ablation was done and a pacemaker implanted. This actually stopped the signals from the av node - now the pacemaker sends the signals.
Perhaps a pacemaker would help when the av node "acts up" ?
In order to keep the heart rate sufficently fast, Doctors sometimes need to implant a Pacemaker that will discharge only when the SA Node fails to fire. This type of Pacemaker monitors the heart, and if the SA Node goes too long without firing, the Implanted Pacemaker will discharge, therefore keeping the heart rate fast enough. If the SA Node works as expected, the Implanted Pacemaker does not do anything, just monitors.
AV Node ablation seems like a drastic decision for SVT. To do so destroys the AV node and requires the use of a pacemaker. If you're not using a pacemaker, then you were ablated in some other area of your heart. Hopefully, this is the case. Please elaborate, so the proper response can be given.
my heart Dr. said that I need a av node ablation and a pace maker, it scares me and I would like to know if it is safe. I am 69 years old. Thank You Jo

Also, the med helps stable the heart rate, but if the sinus node pacemaker output is abnormal, the heart rate could be slow enough to cause formation of blood clots and a heart attack or too fast causing the heart to be unable to pump enough blood into circulation with each heartbeat and cause heart failure.
When I had my AV Node ablation in July I had a two-lead pacemaker implanted. Since then, I have chronic A-Fib. Sometimes I feel the procedure done me more harm than good. I still take flecainide 100 mg. It does not stop the A-Fib, but I cannot manage without it because of symptoms. The top lead has been turned off. I understand the electrical signal begins from the SA Node, and when the rt.
P.s., since they said the issue is with the top part of his heart this probably means they aren't seeing any P waves which implicates the Sinus node. The 30 bpm is probably something called "escape rhythm". The ventricles start to beat on their own if the sinus node beat doesn't arrive in time. It's a backup system, but escape rhythm is much slower than the heart's normal pacemaker the sinus node.
1, which means that every other heart beat originating from the natural pacemaker of the heart (the sinus node) was getting through the atrioventricular node (AV node), the single electrical connection from the top of the heart to the bottom of the heart. This means that the actual heart rate and cardiac output was decreased.
Without seeing your child’s ECG and evaluating your child, I cannot give you specific information.
All surgeries have some risk, but I think catheter surgery (done with catheters through an artery) are among the lest dangerous.
You didn't say why you are considering surgery. If the "problem" is minor you may want to consider living with it rather than take any risk. Talk it over with your doctor.
The worst I've read that I think can be a bad outcome of sinus node surgery is the sinus node shuts down and one then has to have a pacemaker implanted.
We need to wait for more expert input, but in my simple understanding if you had the AV node (fully) ablated you are under full-time pacemaker control. This I think would limit your physical load capabilities. You didn't say what exactly was done to the AV node...that is there may be other AV node ablation procedures than what I assumed in my first statement.
There are many pacemaker patients on the Community, perhaps one or more will respond.
In 1999 I had a pacer implanted after an AV node ablation, indicated for a-fib/ flutter. I am pacemaker dependent. My docs said I had to wait till I was"eri" for a replacement, but the insurance company said I could have one every three years with out a letter of medical necessity. I am anxious to have it replaced due to my dependence: but don't want to rush unnecessarily.
Most of the time though when somebody refers to tachycardia, they are referring to a sinus tachycardia meaning the rate is coming from the sinus node (this is the normal pacemaker for the heart) and is greater than 100 bpm. The only reason why a rhythm is originating from somewhere other than the sinus node is because there is some abnormality.
I am a 43yr old female, and had an av node ablation in 99. I am pacemaker dependent from the procedure.(means my heart no longer beats on its own) I feel much less tired, an was able to regain a pretty normal life after the procedure. I thank God every day for it. I was able to stop taking cardiac meds. which helps lessen the tiredness too. Research complications of this procedure before proceeding and discuss this with your mom and her doctor, knowledge is power! stay strong!
I have heard that can happen with an avnrt ablation, the av node gets blocked and a pacemaker is needed. It is the biggest complication from that type of ablation but I have also heard that it can occur but once the heart settles down and maybe isn't swollen or something it goes away which is probably what your ep is hoping. I do hope that if this is the case with you that yours corrects itself. I think going in and out may be a good sign it will go away.
If your pacemaker was placed because of damage to the AV node, your pacemaker is permanent. Without it, you would have no conduction to the ventricles, meaning you would most likely have a pulse in the 20s or 30s without the pacer. Chances are, if they put a pacer in during your ablation, and it wasn't planned before, it's probably going to be there for life.
As for the recurring tachycardia, this is very normal after an ablation.
Here is an excellent web page discussing Bradycardia and possible causes.

There is a nice graphic showing the construction of the heart, the SA Node (the heart's natural pacemaker), the AV Node (discharges in reaction to the SA Node Discharge or can Discharge Spontaneously if the SA Node fails to discharge in time.
