Atrial Fibrillation

Atrial fibrillation, or afib, is a type of irregular heartbeat (arrhythmia) caused by faulty electrical impulses in the upper chambers of the heart, called the atria. Symptoms include heart palpitations, fatigue, shortness of breath, chest pain, and dizziness. Afib can increase your risk of a heart attack, stroke, cardiac arrest, or heart failure. Although it can't be cured, your doctor can help you manage the condition and reduce the risk of complications with medications, surgery, and other procedures. Eating a healthy diet, exercising, not smoking, and limiting alcohol are ways to lower your risk.

Common Questions & Answers

If I'm experiencing symptoms of afib, when should I contact my doctor?

Call your doctor right away if you think you're experiencing symptoms of afib. If you have recurring afib, wearable devices and apps can help you monitor your heartbeat at home, under the supervision of your doctor.

In some people, afib will go away on its own and not cause any complications. In others, it can get worse, last for years, or even become permanent.

It depends on your afib and health history. Some people may have to continue taking antiarrhythmic medications after ablation, but many will end up no longer needing them.

Having other heart conditions, obesity, sleep apnea, hyperthyroidism, diabetes, chronic kidney disease, or lung disease all increase your risk of afib. Older age, family history, European ancestry, and lifestyle choices also affect your risk.
