With AFib, your heart quivers, beats irregularly, or skips beats. It can't pump blood through its chambers and out to your body as well as it should. Sometimes blood can pool in the heart and form clots, which could lead to a stroke.
Treatments such as medications, nonsurgical procedures, and surgery can slow your heartbeat and bring it back into a normal rhythm. AFib treatments can also prevent clots and help keep your heart healthy.
What Are Some Medications That Treat AFib?
These can prevent clots and strokes, slow your heart rate, and control your heart rhythm.
Blood thinners: These medications thin your blood to lower your chance of having those problems. But they can raise your risk of bleeding, so you might have to cut back on some activities that can lead to injuries. The most common are:
Blood thinners can make you more likely to bruise or bleed too much. You'll see your doctor for a blood test every month to make sure the medication is working and you're on the right dose.
Heart rate medicines: The most common way to treat atrial fibrillation is with drugs that control your heartbeat. These slow your rapid heart rate so your heart can pump better.
You may need other drugs. Some are called beta-blockers. They also slow your heart rate. Some examples are:
- Atenolol (Tenormin)
- Bisoprolol (Zebeta, Ziac),
- Carvedilol (Coreg)
- Metoprolol (Lopressor, Toprol)
- Propranolol (Inderal, Innopran)
- Timolol (Betimol, Istalol)
Others are known as calcium channel blockers. They slow your heart rate and tone down contractions. You might get:
Heart rhythm medicines: They slow the electrical signals to bring your heartbeat into what’s called a normal sinus rhythm. These treatments are sometimes called chemical cardioversion:
Sodium channel blockers, which slow your heart's ability to conduct electricity:
Potassium channel blockers, which slow the electrical signals that cause AFib:
You might get them in your doctor's office or at a hospital. Your doctor will monitor you to make sure the medicine is working.
What Are Some Procedures to Treat AFib?
If medicines don't work or they cause side effects, you can try one of two procedures called cardioversion or ablation. These treat AFib without surgery.
Electrical cardioversion: The doctor gives your heart a shock to regulate your heartbeat. They’ll use paddles or stick patches called electrodes onto your chest.
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.
Most people only need one. Because you’re sedated, you probably won’t remember being shocked. You can usually go home the same day.
Cardiac ablation: There are two major options:
Catheter ablation, also called radiofrequency or pulmonary vein ablation, isn’t surgery, and it’s a less invasive ablation option. Your doctor puts a thin, flexible tube into a blood vessel in your leg or neck. Then they guide it to your heart. When it reaches the area that’s causing the arrhythmia, it sends out electrical signals that destroy those cells. The treated tissue helps get your heartbeat regular again.
There are two main types of catheter ablation:
- Radiofrequency ablation: The doctor uses catheters to send radiofrequency energy (similar to microwave heat) that creates circular scars around each vein or group of veins.
- Cryoablation: A single catheter sends a balloon tipped with a substance that freezes the tissues to cause a scar.
Surgical ablation involves cutting into your chest:
Maze procedure: This is usually done while you’re having open-heart surgery for another problem, like a bypass or valve replacement. The surgeon makes small cuts in the upper part of your heart. They’re stitched together to form the scar tissue that stops abnormal signals.
Mini maze: Most people with AFib don’t need open-heart surgery. That’s where this less invasive option comes in. The doctor makes several small cuts between your ribs and uses a camera to guide catheters for either cryoablation or radiofrequency ablation. Some hospitals offer robot-assisted surgery that uses smaller cuts and allows for greater precision.
Convergent procedure: This pairs catheter ablation with a mini maze. The doctor uses radiofrequency ablation in the pulmonary vein, and a surgeon makes a small cut under your breastbone to use radiofrequency energy on the outside of your heart.
AV node ablation: You might get this procedure if:
- You don’t respond to medications
- You can’t take medications because of side effects
- You aren’t a good candidate for a procedure that cures you.
Your doctor will insert a catheter into a vein in your groin and slide it up to the AV node, a nerve that conducts electrical impulses between the top and bottom chambers of your heart. They’ll send radiofrequency energy through the catheter to destroy the AV node. This stops the signals from reaching your ventricle. Then the doctor will implant a pacemaker into your chest.
For some people, ablation restores a normal heart rhythm better than medicine. It’s generally safe, but it does have some risks. Some of the things that can go wrong are:
Also, your AFib can come back in the first few months after you have ablation. In that case, you may need to have the procedure again or take heart rhythm drugs.
This is a small device that monitors your heartbeat and sends out a signal to stimulate your heart if it's beating too slowly. It’s made up of a small device called a generator that holds a battery and a tiny computer. Very thin wires called leads connect the pacemaker to your heart.
Getting a pacemaker may sound like a big deal, but it's a minor procedure. First, your doctor inserts a needle into a large vein near your shoulder, which guides the leads into your heart. The pacemaker then goes into your chest through a small cut. Once it's in place, your doctor tests it to make sure it works.
There are some risks, such as:
- Bleeding or bruising in the area where your doctor places the pacemaker
- Damaged blood vessel
- Collapsed lung
- If there are problems with the device, you may need another surgery to fix it.
Sometimes the impulses your pacemaker sends to your heart can cause discomfort. You may be dizzy or feel a throbbing in your neck.
Once you have one put in, you might have to keep your distance from objects that give off a strong magnetic field because they could affect the electrical signals from your pacemaker.
Some devices that can interfere with it are:
- Metal detectors
- Cell phones and MP3 players
- Electric generators
- Some medical machines such as an MRI
Treating the Causes of AFib
If problems such as high blood pressure, cholesterol, or an overactive thyroid caused your AFib, you'll need to treat the root cause. Your doctor might prescribe medications to get those conditions under control.
Your doctor may also recommend screening and treatment for sleep apnea, a disorder in which breathing starts and stops throughout the night.
We need more research into alternative and complementary treatments for AFib. But a few have shown some promise in early studies. They include:
- Omega-3 fatty acids
- Antioxidant vitamins, such as Vitamins C and E
- Herbal supplements like berberine, cinchona bark, and shenshongyanxin (a traditional Chinese mixture)
Always check with your doctor before you try a complementary treatment.
Your doctor also might recommend you take some simple steps to help keep your heart healthy:
- Change your diet -- eat heart-healthy, low-salt food. Go for fruits, veggies, and whole grains.
- Get more exercise -- more physical activity strengthens your heart
They'll probably suggest that you make other changes to lower your odds of heart disease, as well as conditions like diabetes and lung disease that can contribute to AFib:
Your doctor will likely advise you to avoid stimulants, which can trigger AFib episodes. These include over-the-counter cough medicines that contain pseudoephedrine as well as recreational drugs like cocaine and amphetamines.
Don't overlook your emotional health. Stress may make atrial fibrillation worse, so find ways to manage it. You might try:
