FAQ

Atrial fibrillation (AFib) is not generally considered curable in the sense that once diagnosed, it is often a lifelong condition requiring ongoing management. However, for some patients—particularly those with early-stage or paroxysmal (intermittent) AFib—treatments can effectively eliminate the arrhythmia, leading to long-term remission or what some describe as a "cure" in select cases.

Common causes include high blood pressure, heart disease, thyroid issues, excessive alcohol or caffeine, sleep apnea, and aging. It can also occur without a clear cause (lone AFib). Risk factors include obesity, diabetes, and family history.

Many people are asymptomatic, but common symptoms include palpitations, shortness of breath (especially during exertion), fatigue, chest pain, dizziness, or confusion.

The greatest risk is stroke, as AFib increases stroke risk up to five times due to blood clots forming in the heart. Other risks include heart failure, chronic fatigue, and reduced quality of life.

Diagnosis often involves an electrocardiogram (ECG or EKG) to detect irregular rhythms, along with blood tests, echocardiograms, stress tests, or wearable monitors like Holter devices for ongoing tracking.

Yes, there can be a genetic component; if a close relative has AFib, your risk may increase, though lifestyle and other factors play a larger role.

AFib itself is rarely fatal, but untreated it can lead to serious complications like stroke or heart failure, which can be life-threatening.

Both are arrhythmias, but atrial flutter involves a more organized, rapid circuit in the atria, while AFib is more chaotic. They share similar symptoms and risks but may require different treatments.

Key questions include: What's my stroke risk (e.g., CHADS-VASc score)? Should I focus on rate or rhythm control? Do I need anticoagulation? What lifestyle changes can help?
