What Is Atrial Fibrillation (AFib)?
Atrial fibrillation, or AFib, is a common type of irregular heartbeat. It happens when the upper chambers of the heart (called the atria) beat out of sync with the lower chambers (the ventricles). Instead of a steady, regular rhythm, the heart may beat too fast, too slow, or in a chaotic way.
What Does It Feel Like?
Some people with AFib don’t feel any symptoms, but others may experience:
- A fluttering or pounding heartbeat (palpitations)
- Feeling tired or weak
- Dizziness or lightheadedness
- Shortness of breath
- Chest discomfort
Symptoms can come and go or they can last all the time, depending on the type of AFib.
Why Is AFib Important?
AFib is not just an irregular heartbeat, it can raise your risk of other serious health problems. The biggest concern is stroke. When the heart does not pump properly, blood can pool and form clots. If a clot travels to the brain, it can cause a stroke. AFib can also lead to heart failure if not managed well.
What Causes AFib?
AFib can happen for many reasons. Some common causes include:
- High blood pressure
- Heart disease
- Sleep apnea
- Drinking too much alcohol
- Stress or illness
- Sometimes, no clear cause is found
How Is AFib Treated?
Treatment depends on your symptoms, how long you have had AFib, and your risk of stroke. Your doctor may recommend:
- Medications to control your heart rate or rhythm
- Blood thinners to reduce the risk of stroke
- Cardioversion, a procedure to reset your heart rhythm
- Ablation, a treatment that targets the area causing the irregular beats
In some cases, a small device like a pacemaker may be needed.
Can I Live a Normal Life with AFib?
Yes. Many people with AFib live full, active lives with the right treatment and follow-up care. It’s important to:
- Take your medications as prescribed
- Go to regular checkups
- Keep your blood pressure and other conditions under control
- Limit alcohol and caffeine
- Stay active with your doctor’s guidance
