What Is Atrial Fibrillation?

Atrial fibrillation (AFib) is the most common sustained cardiac arrhythmia, affecting more than 6 million Americans. In AFib, the heart’s upper chambers (atria) fire chaotically instead of contracting in a coordinated, organized rhythm. This produces an irregular, often rapid heartbeat that reduces the heart’s pumping efficiency and — most critically — dramatically increases the risk of blood clot formation in the left atrial appendage, leading to stroke.

AFib affects approximately 1 in 10 adults over age 65 and is a leading cause of stroke, heart failure, and cardiovascular hospitalization. Early diagnosis and comprehensive management are essential.

Types of Atrial Fibrillation

Paroxysmal AFib — Episodes that start and stop on their own, typically lasting less than 7 days. Even brief episodes carry stroke risk and warrant treatment.

Persistent AFib — Continuous AFib lasting more than 7 days that requires medical or electrical cardioversion to restore normal rhythm.

Long-Standing Persistent AFib — Continuous AFib lasting more than 12 months.

Permanent AFib — When restoration of normal sinus rhythm is no longer pursued as a treatment goal; focus shifts to rate control and stroke prevention.

AFib Symptoms

• Palpitations — irregular, rapid, or “fluttering” heartbeat
• Shortness of breath at rest or with exertion
• Fatigue and reduced exercise tolerance
• Dizziness or lightheadedness
• Chest discomfort or pressure
• Some patients with AFib have no symptoms at all (asymptomatic AFib)

Our AFib Treatment Approach

Stroke Risk Stratification & Anticoagulation — We calculate your CHA₂DS₂-VASc score to determine your stroke risk and prescribe anticoagulation therapy (blood thinners) when indicated. We manage direct oral anticoagulants (DOACs) including apixaban, rivaroxaban, dabigatran, and edoxaban, as well as warfarin with INR monitoring.

Rate Control — Medications such as beta-blockers, calcium channel blockers, or digoxin are used to slow the ventricular response rate and reduce AFib symptoms. The goal is typically a resting heart rate below 80 bpm.

Rhythm Control — For appropriate patients, we pursue restoration and maintenance of normal sinus rhythm using antiarrhythmic medications (flecainide, propafenone, amiodarone, sotalol, dofetilide) or electrical cardioversion.

Cardioversion — Direct current cardioversion to restore normal sinus rhythm in persistent AFib. Performed in a monitored setting with appropriate anticoagulation bridging.

Ablation Referral — For patients with symptomatic, drug-refractory AFib, we coordinate timely referral to electrophysiology specialists for pulmonary vein isolation (catheter ablation) — the most effective rhythm control strategy.

AFib Risk Factor Management

AFib risk factors that are modifiable include hypertension, obesity, obstructive sleep apnea, excessive alcohol consumption, hyperthyroidism, and physical deconditioning. Comprehensive AFib management addresses all modifiable risk factors alongside direct arrhythmia treatment — an approach shown to reduce AFib recurrence and improve outcomes.

Frequently Asked Questions

Can AFib go away on its own?

Paroxysmal AFib episodes often stop spontaneously within hours to days. However, without treatment, episodes typically become more frequent and prolonged over time. Even self-terminating AFib carries stroke risk and should be evaluated and treated by a cardiologist.

What is the most effective treatment for AFib?

Treatment effectiveness depends on AFib type, symptom burden, and underlying causes. For paroxysmal and persistent AFib, catheter ablation (pulmonary vein isolation) has the highest success rate for maintaining sinus rhythm. Antiarrhythmic medications are effective for many patients. Stroke prevention with anticoagulation is essential regardless of rhythm strategy.

Can I live a normal life with AFib?

Yes. With proper treatment — anticoagulation to prevent stroke, rate or rhythm control to reduce symptoms, and risk factor modification — the vast majority of AFib patients live full, active lives. Regular cardiology follow-up is important for optimizing and adjusting your treatment over time.

What foods and drinks should I avoid with AFib?

Alcohol is a major AFib trigger — even moderate consumption increases AFib recurrence. Excessive caffeine, energy drinks, and stimulants should be limited. If you are on warfarin, consistent vitamin K intake (green vegetables) is important. A heart-healthy diet low in processed foods, sodium, and saturated fat supports overall cardiovascular health.

Is AFib a hereditary condition?

There is a significant genetic component to AFib. Having a first-degree relative with AFib increases your lifetime risk. However, modifiable risk factors including hypertension, obesity, and sleep apnea play a larger role in most patients.
