What are the risks of cardioversion?
Major risks of cardioversion include: Dislodged blood clots. Some people who have irregular heartbeats have blood clots in their hearts. Electric cardioversion can cause these blood clots to move to other parts of your body. This can cause life-threatening complications, such as a stroke or a blood clot traveling to your lungs.
What to expect after cardioversion procedure?
WHAT TO MONITOR ONCE AT HOME
- Check your temperature – A temperature of 101 or greater may be an early sign of infection.
- Weight – If elevated, you may be asked to take a diuretic to help remove fluid retained after your procedure.
- Resume normal activity after a week, but avoid any strenuous activities for 2 weeks, such as the gym.
- Do not drive for 2 days post procedure.

- Wake up 5 to 10 minutes after the procedure
- Be closely watched for signs of complications for several hours
- Feel sleepy for several hours after the cardioversion. Arrange to have someone drive you home
- Go home the same day as the procedure
- Have some redness or soreness on your chest that lasts for a few days

Cardioversion itself takes about 5 minutes. But the whole procedure, including recovery, will probably take 30 to 45 minutes. You may take an anticoagulant medicine before and after cardioversion.
How often does AFib return after cardioversion?
Many people who have had successful cardioversion develop atrial fibrillation again. According to studies, this happens within a year in up to 80 out of 100 people. The success rate can be improved somewhat by taking anti-arrhythmic medication over the longer term.
Is cardioversion more successful the second time?
With the second attempt of ECV, 72/94 (76.6%) patients were converted to SR. Patients had a more favorable outcome with the 2nd ECV as compared to initial ECV (76.6% vs 62.67%, p = 0.042). Results of serial electrical cardioversion in atrial fibrillation and follow-up over one year.

What heart rate is too high with AFib?
The most obvious symptom of atrial fibrillation (AF) is palpitations caused by a fast and irregular heartbeat. A normal heart rate, when you are resting, should be between 60 and 100 beats a minute. In atrial fibrillation, it may be over 140 beats a minute.
How long can you live with permanent AFib?
Overall survival of patients with lone atrial fibrillation was 92% and 68% at 15 and 30 years, respectively, similar to the 86% and 57% rates for the age- and sex-matched Minnesota population (P=0.12, log-rank test; Figure 3A). Of the 76 patients with lone atrial fibrillation, 27 died during the 30-year follow-up.
Does AFib ever go away?
Paroxysmal atrial fibrillation is one of the types that starts suddenly and goes away own on its own. However, patients should still be monitored and treated. Usually, atrial fibrillation is permanent, and medicines or other nonsurgical treatments can't restore a completely normal heart rhythm.
Is cardioversion a high risk procedure?
Potential risks of electric cardioversion include: Dislodged blood clots. Some people who have irregular heartbeats, such as A-fib, have blood clots form in the heart. Shocking the heart can cause these blood clots to move to other parts of the body.

Does cardioversion cure AFIB?
While electrical cardioversion may be effective at converting the heart back into normal sinus rhythm, it has a low success rate in keeping it there, and thus may require multiple tries. It also doesn't cure afib.
Does cardioversion cure atrial flutter?
Atrial flutter — Atrial flutter is an atrial arrhythmia that can be treated with cardioversion. The success rate is over 90 percent. Success is not related to the duration of this arrhythmia. Anticoagulation is also given prior to and after cardioversion, as it is in patients with AF.

Electrical cardioversion is more than 90% effective, though many have AFib again shortly after having it. Taking an antiarrhythmic drug before the procedure can prevent this. How well it works depends on the size of your left atrium as well as how long you’ve been in AFib. If you have a large left atrium or you’ve been in constant AFib for a year or two, it may not work as well. Taking antiarrhythmic drugs can also prevent AFib after a successful electrical cardioversion.

What Is The Success Rate of Cardioversion?
What is the main benefit of doing a cardioversion? The main benefit is to get someone out of Atrial Fibrillation. But how well does a cardioversion actually work? Does it actually get someone out of atrial fibrillation? I usually tell my patients that the cardioversion itself usually works very well. In my experience, the actual shock treatment works probably about 90% of the time to actually get a patient out of atrial fibrillation. Now, that doesn't mean the atrial fibrillation can't come back. There's an inherent short circuit problem or a problem with a patient’s heart which is triggering episodes of atrial fibrillation, so, the AFib may come back an hour later, a week later, or a year later, there is no good method to predict if or when the AFib will come back. Usually, changes in medication or lifestyle modifications are required after the cardioversion in order to help keep you in a normal rhythm and improve the success rate.
How to do elective cardioversion?
In my case, I usually schedule the procedure with an anesthesiologist. You get an intravenous put in place, once everything is ready, you get heavy sedation medication which will only put you to sleep for a few minutes, and once you're asleep we apply this electrical current to your heart to help reset your heart. Typically, it only takes a few seconds to do. Once you're awake, typically patients can go home. Again, I typically provide medication adjustments after a cardioversion in order to improve the success rate of the procedure and to keep the AFib from coming back.
What Is A Cardioversion?
First of all, what is a cardioversion? A cardioversion is an electrical shock to your heart to try to reset your heart, to get you out of atrial fibrillation, and back to normal sinus rhythm. You may have seen on TV, or in a movie when someone's heart stops, and they take the electrical paddles and give them the electrical shock to bring them back to life. Meanwhile, your favorite actor will usually yell-“Everyone Clear!”
Who Is A Candidate For A Cardioversion?
A cardioversion is only beneficial for people who are in what's called Persistent At rial Fibrillation which means you are in Atrial Fibrillation all the time. If your AFib episodes come and go, meaning they usually stop on their own, then a cardioversion is not the right treatment for you. But if you're in AFib consistently, it may be a beneficial treatment option for you. However, I will say when it comes to the success rate of a cardioversion, the longer somebody is in Atrial Fibrillation, the less likely the cardioversion will be successful.
How Much Energy (Also Known As Joules) Is Typically Needed During A Cardioversion?
In addition, the longer someone is in atrial fibrillation, the more energy is required to be successful to cardiovert someone. Someone who has been in persistent atrial fibrillation for a few weeks will typically require less energy then someone that has been in persistent atrial fibrillation for over one year. I use 200 Joules most of the time during a cardioversion for atrial fibrillation.
Does your chest hurt after cardioversion?
There are a few patients that experience chest pain after a cardioversion, but it is not chest pain from your heart. It is usually pain on your skin where the shock was delivered. The more energy that was needed to perform a cardioversion, the more likely there will be some pain after the procedure. Some patients also get a rash or redness on their skin from where the cardioversion pads where placed. However, most of these symptoms are very mild and resolve within a few days.
When Do I Recommend A Cardioversion?
I can offer them cardioversion on the same day or the next day to help get them out of AFib and improve their symptoms. Long term, other options such as an ablation may work better, but in the short term, a cardioversion can be a very useful treatment option.
What are the risks of cardioversion?
If you have atrial fibrillation, blood clots can form in your heart’s left atrium. Cardioversion may knock loose a blood clot in your left atrium. If the clot (embolus) travels to your brain, it can cause a stroke. To avoid this, your doctor may give you medicine (such as warfarin) to make your blood less likely to form blood clots. If your doctor gives you the medicine, you’ll need to take it for 2 to 3 weeks before the procedure. Transesophageal echocardiography (TEE) is often used to check for the presence of blood clots before this procedure.
Why do people have cardioversion?
People have non-emergency or elective cardioversion to treat arrhythmias. The electrical signals that control your heartbeat start in the upper right chamber of your heart (atrium). In atrial fibrillation, very fast, irregular electrical signals move through both of the upper chambers of your heart. This can make your heartbeat fast and irregular. Some people who have atrial fibrillation don’t notice any changes in the way they feel. But others feel:

What is the difference between chemical and electrical cardioversion?
There are two types of cardioversion: Chemical cardioversion involves taking medication to convert your rhythm. Electrical cardioversion sends an electrical shock to your heart to restore its normal rhythm. Electrical cardioversion for afib usually works right away, but afib often comes back.
How long does it take for AFIB to return?
Cardioversion restores a normal heartbeat rhythm 90% of the time. However, more than half of these people develop afib again after one year. When this happens, people sometimes have another electrical cardioversion. If afib returns again, chances are even lower for a third procedure to work.
Why do people have AFIB surgery?
People who have surgery for afib usually do so because other treatments have not worked for them. It's also an option for people with afib who are having surgery for another heart condition, such as a damaged heart valve. Surgery for afib usually has a high success rate.
What is the treatment for AFIB?
If cardioversion isn't an option for you or you tried it and afib returned, you may be a candidate for a treatment called ablation. Cardiac ablation destroys specific areas of heart tissue causing your irregular heart rhythm. Your doctor may use freezing ( cryotherapy ), lasers, or electrical energy (radio frequency) to do this.
Why does my heart beat so fast?
You might feel like you’re running a marathon, even if you’re sitting down. This happens because irregular electrical signals are moving through your heart. Some people don’t notice warning signs of this.
