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.

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.

Sinus (Definition)

In anatomy, a sinus is a cavity within a bone or other tissue. Most commonly found in the bones of the face and connecting with the nasal cavities. Sinus (anatomy), description of the general term paranasal sinuses, air cavities in the cranial bones, especially those near the nose, including: the maxillary sinuses, also called the maxillary antra and the largest of the ...Read more

How risky are ablations of the sinus node?

How risky are ablations of the sinus node?

Depends.: All procedures have risks, some risks are more likely to happen with some procedures, and less with others. Sinus node ablation is safer than open heart surgery, for example, but is not risk free. Your doctor is required to explain what the risks are for the patient, and this depends on the condition of the patient at the time of the procedure as well. Ask the doc questions until you understand

Hi I have inappropriate sinus tachycardia and how do doctors know if its the sinus node or nervous system? Is that why some ablations don't work?

Hi I have inappropriate sinus tachycardia and how do doctors know if its the sinus node or nervous system? Is that why some ablations don't work?

Combination: Inappropriate sinus tachycardia (ist) is a difficult entity to treat with ablation. You want to be able to reduce the heart rate enough without leaving the person requiring a pacemaker. A newer medication ivabradine may be used off-label for ist. Good luck.

Will a AV node ablation for sure 100 present fix my heart from going to fast & slow.?

Will a AV node ablation for sure 100 present fix my heart from going to fast & slow.?

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.

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

What is the indication for surgical ablation (av node ablation) for atrial fibrillation?

What is the indication for surgical ablation (av node ablation) for atrial fibrillation?

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.

With a pacemaker implant and an AV Node ablation, why would you want to pace the atria but not the ventricles?

With a pacemaker implant and an AV Node ablation, why would you want to pace the atria but not the ventricles?

Pacing: AV node ablation requires ventricular pacing or atrioventricular pacing, atrial only is not appropriate in AV block.

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.?

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.

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.

Why would I be completely be dependent on my pacemaker if I have the AV node ablation Such as SVT are atrial fibrillation?

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

Cardiac ablation question. When do you need it?

Cardiac ablation question. When do you need it?

Recurrent arrhythmia: If one has recurrent fast heart beat or irregular heart beat (svt, afib etc) and symptomatic, cardiac ablation may be needed if medications could not control the rate and rhythm.

What can I expect when going in for a cardiac ablation?

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.

What are some possible complications of a cardiac ablation?

What are some possible complications of a cardiac ablation?

Partial List: 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 bleeding cardiac perforation risk of pacemaker stroke 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.

What are the advantages and disadvantages of cardiac ablation?

Short List: Advantages: potential permanent fix no need for lifetime meds (often) feeling of "doing something about it" disadvantages: 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).
