Does cardioversion cause pain during procedure?
You should not feel any pain. Your doctor puts patches on your chest or on your chest and back. Cardioversion itself takes about 5 minutes. But the whole procedure, including recovery, will probably take 30 to 45 minutes.
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 are the side effects of cardioversion?
You will likely:
- 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
Can cardioversion damage your heart?
There is no evidence that the cardioversion per se damages the heart in any way. The major risks of the procedure (again, assuming proper preparation, see below) are related to the anesthesia. I am more inclined to recommend a repeat cardioversion if there is clear-cut evidence that the patient does poorly when the heart is in afib.
How long does it take to recover from a cardioversion?
What is the recovery time? You'll most likely go home the same day as your cardioversion. However, you can't drive for 24 hours because you'll be sleepy from the anesthesia. You'll be able to eat and drink after your procedure.
How will I feel after a cardioversion?
After the procedure, you may have redness, like a sunburn, where the patches were. The medicines you got to make you sleepy may make you feel drowsy for the rest of the day. Your doctor may have you take medicines to help the heart beat normally and to prevent blood clots.
Are you awake during cardioversion?
Because the shock would be painful for a patient who is awake, an intravenous medication is given to sedate the patient. Patients are asleep during the cardioversion and most do not remember the procedure. It is not usually necessary to have a breathing tube (endotracheal tube) placed before the procedure.
Is there pain after cardioversion?
Your chest wall and chest muscles may feel sore for a few days. Some redness may appear on the skin on your chest where the cardioversion patches were applied. That will go away within a week. To get ready for this procedure, you may have been given medicine to help you relax and to reduce pain.
Will I feel better immediately after cardioversion?
After cardioversion, many people feel immediate relief from their arrhythmia symptoms. You may need to receive further treatment or take medications to continue to treat arrhythmia.
Should I be worried about cardioversion?
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.
What next if cardioversion does not work?
Repeat cardioversions can be performed. If the rhythm still doesn't stabilize, patients may be referred for catheter ablation, a procedure that destroys the heart tissue causing the irregularity.
Does cardioversion weaken the heart?
It might make things worse: It's unlikely, but there's a small chance that cardioversion could damage your heart or lead to more arrhythmias. Irritated skin: This often happens where the paddles are applied. The doctor can give you a cream to treat it.
How long do you have to be in AFib before cardioversion?
Time to Cardioversion for Acute Atrial Fibrillation and Thromboembolic Complications. In 1995, practice guidelines recommended a limit of 48 hours after the onset of atrial fibrillation (AF) for cardioversion without anticoagulation.
Are there any restrictions after a cardioversion?
Do not drive until the day after a cardioversion. You can eat and drink when you feel ready to. Your doctor may have you take medicines daily to help the heart beat in a normal way and to prevent blood clots. Your doctor may give you medicine before and after cardioversion.
How many Cardioversions can a heart take?
There is really no limit to the number of cardioversions that people can have but at some point of time, we figure out that either it is a futile strategy or patients tend to get frustrated. But when it is a necessity that our patients who've had 20, 25 cardioversions also.
Is cardioversion considered surgery?
Cardioversion treats cardiac arrhythmias, or abnormal heartbeats. It uses medicines or low-energy electrical shocks to restore a normal heartbeat. Many times, cardioversion is an elective procedure.
Are there any restrictions after a cardioversion?
Do not drive until the day after a cardioversion. You can eat and drink when you feel ready to. Your doctor may have you take medicines daily to help the heart beat in a normal way and to prevent blood clots. Your doctor may give you 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.
What does cardioversion do to the heart?
Cardioversion upsets the abnormal signaling and lets the heart to reset itself back into a normal rhythm. Cardioversion is usually a scheduled procedure. But sometimes healthcare providers need to do it as an emergency . This is done if symptoms are severe.
Can you drink coffee after cardioversion?
Despite prior concerns, experts have concluded that coffee and tea are safe for patients with an abnormal heart rhythm, based on a review of all available evidence. Published in JACC: Clinical Electrophysiology, this study looked at the impact of caffeinated beverages on heart rhythm.
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:
How does an IV shock work?
You won’t feel pain during the procedure. Your doctor will deliver an electrical shock through two paddles. One is placed on your chest and the other on your back.
What is cardioversion used for?
Cardioversion also treats other kinds of abnormal heartbeats, including atrial flutter, atrial tachycardia and ventricular tachycardia. Cardioversion or defibrillation is also used in emergency situations for people who suffer sudden life threatening arrhythmias.
What is abnormal heart rhythm called?
Abnormal heart rhythms are called arrhythmias. Watch an animation of arrhythmias. There are two kinds of cardioversion. Your doctor may give you one or more medicines to bring back your regular heartbeat. This is called pharmacologic (chemical) cardioversion.
How many shocks do you need for a heart attack?
The shock lasts less than a second, and briefly stops (resets) your heart rhythm. Your doctor will check to see if your heartbeat is regular. Some people need only 1 shock .
What are the side effects of electrical cardioversion?
Some side effects of electrical cardioversion include pain and irritation at the site of the electrodes, soreness in the chest, and anxiety. As noted above, the best management for after electrical cardioversion is to provide the patient with sedation. Pain medication may also be administered if the patient's pain is significant.
What are the two most common types of cardioversion?
The types of cardioversion that might be performed by either a medical professional or a lay rescuer depend mainly on the medical condition experienced by the patient and on the severity of the patient's condition. Electrical and pharmacological are the two most common types of cardioversion.
What is the conversion of a cardiac (heart) arrhythmia into an alternative cardiac rhythm?
Cardioversion is the conversion of a cardiac (heart) arrhythmia into an alternative cardiac rhythm. Cardioversion refers to a variety of medical procedures. The most common involve either medications (pharmacological cardioversion ) or electricity (electrical cardioversion or defibrillation). 1 Which method is used depends on the patient's condition and overall stability.
Why is cardioversion used for pharmacological solutions?
Use of the term cardioversion for pharmacological solutions is less common, probably because there is a variety of uses for medications that might cause an immediate change in the heart rhythm —traditionally known as cardioversion—but can also be used chronically to control heart rate or rhythm .
How does electrical cardioversion work?
Process. Electrical cardioversion uses electrodes that are several inches across to conduct electricity through the heart muscle. The electrodes can be placed externally on the chest wall or internally directly on the heart muscle. There are different types of electrical cardioversion, but they all use the same device known as a defibrillator.
Why is sedation used after cardioversion?
In the event the patient is not stable enough to wait for sedation before cardioversion, sedation is often used after the fact to help the patient manage discomfort post-shock. Patients often report a retrograde amnesia effect from the use of sedation after cardioversion and cannot remember the actual procedure.
Is tachycardia synchronized cardioversion?
Synchronized Cardioversion. Some forms of tachycardia are still organized cardiac rhythms but are going at too fast of a rate to adequately allow the heart to effectively pump blood. In these cases, the patients are still able to pump blood and therefore will have a pulse and will most likely be conscious.
What is cardioversion in heart?
Cardioversion is a procedure that can be used to correct many types of fast or irregular heart rhythms. The most common of these are atrial fibrillation and atrial flutter. Cardioversion is also used to correct ventricular tachycardia, which is a very fast, life-threatening heart rhythm that starts in the lower chambers of the heart (ventricles).
Where is cardioversion done?
The cardioversion will likely be done in the electrophysiology (EP) lab.
Can you take Coumadin on cardioversion?
Please ask your doctor how you should take your blood thinners/anticoagulants, such as Coumadin (warfarin), and your diabetes medications or insulin on the day of your cardioversion. Unless your doctor or nurse tells you otherwise, take all other regular medications as scheduled.
Is cardioversion part of a plan of care?
Cardioversion is only one part of your plan of care. It is also important for you to take your medications, a heart-healthy lifestyle and keep your follow-up appointments. Please talk to your doctor if you have any questions or concerns.
What Is Recovery From Cardioversion Like?

How does electrical cardioversion work?
Electrical cardioversion gives shocks through paddles to regulate your heartbeat. First, you'll get medicine to make you fall asleep. Then, your doctor will put the paddles on your chest, and sometimes your back. These will give you a mild electrical shock to get your heart's rhythm back to normal.
Does cardioversion work?
It might not work: Cardioversion doesn't always fix a fast or irregular heartbeat. You may need medicine or a pacemaker to control things.
Is it bad if your heart beats too fast?
If your heart beats too fast or unevenly, it can be dangerous. It may not be pumping enough blood to meet your body's needs. An irregular heartbeat also can lead to a stroke or a heart attack.
Can you get AFIB again after a cardioversion?
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 are the complications of cardioversion?
If you are planning to have cardioversion, your doctor will review a list of possible complications, which may include: Inability to stop the abnormal rhythm. Abnormal rhythm is resumed after a normal rhythm was established. Development of a more dangerous dysrhythmia. Damage to the heart muscle.
What happens if you leave the hospital?
After you leave the hospital, contact your doctor if any of the following occurs: Blisters, redness, or open sores on your chest. Confusion, lightheadedness, or dizziness. Sensation of your heart fluttering (palpitations) Sensation of a skipped or missed hearbeat, or an irregular pulse.
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!”
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 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.
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.
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.
Why is cardioversion important?
Cardioversion upsets the abnormal signaling and lets the heart to reset itself back into a normal rhythm. Cardioversion is usually a scheduled procedure. But sometimes healthcare providers need to do it as an emergency . This is done if symptoms are severe.
What is electrical cardioversion?
Cardioversion is a procedure used to return an abnormal heartbeat to a normal rhythm. This procedure is used when the heart is beating very fast or irregular. This is called an arrhythmia. Arrhythmias can cause problems such as fainting, stroke, heart attack, and even sudden cardiac death. With electrical cardioversion, a high-energy shock is sent to the heart to reset a normal rhythm. It is different from chemical cardioversion, in which medicines are used to try to restore a normal rhythm.
How to check for blood clots in the heart?
Your healthcare provider may want a transesophageal echocardiography test before the procedure. This test is a special kind of ultrasound. A thin, flexible tube is put down your throat and into your esophagus. Here, the tube is close to your heart. It lets your healthcare provider see if you have any blood clots in the heart. Your cardioversion will be delayed if a clot is found. You'll likely need to take blood thinner medicine for a while until your risk of clots is low. It's important to take this medicine (such as warfarin) exactly as your healthcare provider tells you.
How does a cardioversion machine work?
You will receive medicine through a vein in your arm to make you fall asleep. Using the cardioversion machine, a programmed high-energy shock is sent to your heart. This should convert your heart back to a normal rhythm.
How to reset heart rate before cardioversion?
Before trying electrical cardioversion, your healthcare provider may try to reset the heart rate in other ways. This might include the Valsalva maneuver. This is a method where you hold your breath and increase the pressure in your belly.
What is the name of the condition that causes sudden cardiac death?
This is called an arrhythmia . Arrhythmias can cause problems such as fainting, stroke, heart attack, and even sudden cardiac death. With electrical cardioversion, a high-energy shock is sent to the heart to reset a normal rhythm. It is different from chemical cardioversion, in which medicines are used to try to restore a normal rhythm.
What happens if you have a blood clot?
Dislodged blood clot, which can cause stroke, pulmonary embolism, or other problems
