Av Node Ablation Pacemaker
What do the experts think, should my physical fatigue go away after the av node ablation procedure with pacemaker?
A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more
So if I have the AV node ablation why would I be dependent on my pacemaker for the rest of my life? I don't understand why that happens.
Permanent block: Ablation of the AV node results in complete block of all electrical impulses coming from above in the atrium that is permanent. Since there is no impulse to stimulate the lower ventricle from above a spontaneous beat is generated in this chamber but at a much slower rate often in the 30s. Thus the need for a permanent pacemaker since ablation is irreversible ...Read more
With a pacemaker implant and an AV Node ablation, why would you want to pace the atria but not the ventricles?
My heart rate goes real high and real low. Would a AV node ablation help me. I know that it would leave me dependent on my pacemaker.?
This depends on: What is driving your heart rate to be fast. If you already have a pacemaker, you should have a cardiologist and likely an electrophysiologist. You should review a question like this with your heart doctor as he/she will know your history much better and be able to provide a more educated answer. ...Read more
Why would I be completely be dependent on my pacemaker if I have the AV node ablation Such as SVT are atrial fibrillation?
Electricity: The heart is a house with 2 chambers upstairs (atria) and 2 chambers downstairs (ventrical). The electricity to the downstairs chambers comes from the upstairs chamber. The connecting point between the tow floors is called AV node. If you cut this AV node, the lower chambers will not have electricity to work, so u need to provide the lower chamb with anther source of electricity, that is pacemaker ...Read more
How often do cardiac ablation surgeries result in complications requiring pacemakers implantation?
It depends: It depends on the ablation type: almost never for wpw, atrial fibrillation/flutter or ventricular tachycardia; 1% or less for avnrt (atrioventricular nodal reentry tachycardia). In avnrt, there is an extra 'lane' in the av node that conducts electrical impulses leading to tachycardia and the ablation can unintentionally damage the whole av node resulting in heart block and need for pacemaker. ...Read more
Had a cardiac ablation two weeks ago and now my heart ratee is going from 50 to as high as 130 Could that mean a pacemaker Getting an even monitor?
Great question!: Since you've already had an ablation, you already have an expert at your disposal to help answer this question - the same doctor who did your procedure. He or she needs to know your symptoms in order to obtain any additional testing, which may well be an event monitor. Call today! ...Read more
If my blood pressure goes real high and real low would a AV node ablation help me not go fast nor to low? I know I would be dependent on my pacemaker.
AbsolutelyNot, BP is: Determined by the interaction of cardiac output combined with relative opening (Total Peripheral Resistance) of all the arterioles (end arteries just prior to capillaries), body wide, both under direct split-second control from the brain 24/7. The AV node electrically links the atrial & ventricular muscles; does not directly affect cardiac output or TPR. Ablation would make you dependent & worse! ...Read more
Not 100%: Nothing is 100%. The electrocardiologist will do their best to locate the exact location, but there is a chance they can't get it all and it will recur. While it works most of the time I frequently see patients that have had it done and it doesn't completely work. ...Read more
Definitive Control: We don't generally do this with surgery, but rather with a "catheter" based procedure (wire we thread into the heart that cauterizes the av node). This procedure provides complete control of the heart rate in the lower chamber and excellent symptom control, but makes people dependent on the pacemaker that *must* be implanted with this procedure. ...Read more
Me and my doctors have been talking about doing a AV node ablation. How do I talk with my doctors about doing it from my out look on it.
Advise your: Physician that you desire to be actively involved in your health. Explain your concerns, thoughts and ask questions. ...Read more
Sometimes light headed and extremely fatigue 6 days after cardiac ablation, what can cause this? Nicked av node but no PM needed, normal sinus rhythm.
Probably normal, but: Your system is accomodating the changes in your cardiovascular system induced by the ablation. Unless the light-headedness and fatigue are severe, I would give it a few days. You could let your Physician know what's happing; but If not improving, follow up with your PCP and/or cardiologist. ...Read more
To feel better: On a more serious note, you will lay flat on a special table and be draped with a sterile sheet. Your groin will be injected with medicine to numb the skin. Your doctor will usually give you some mild sedation to make you comfortable. During the procedure you may feel palpitations and occasionally some chest or shoulder discomfort. When it's done you wil have to lay flat for a few hours. ...Read more
Usually one: There is usually one nurse and one or two technicians along with the doctor who is performing the procedure. ...Read more
Lots: Cardiac ablations are highly successful procedures to help manage and sometimes cure cardiac dysrhythmias. The key is to find a really good ep doc. ...Read more
It depends on the procedure. There are many ablations and the risks are determined by what structures we're near in the procedure.
Pain at catheter insertion site
risk of pacemaker
damage to coronary arteries
damage to heart valves
good news: the risk of major complications is usually < 4%, *often* <1% w/ an excellent md and the risk of dying is usu < 1:1000. ...Read more
potential permanent fix
no need for lifetime meds (often)
feeling of "doing something about it"
expensive if you pay in cash
carries procedural risks
requires time off work (but not much)
may require repeat procedure
very competent doctor often required to get best results and avoid inadvertent damage. Not all doctors ablate with equal skill (much the same as surgeons). ...Read more
