AFib Care
Atrial Fibrillation Evaluation and Treatment
AFib is the most common heart rhythm disorder, causing an irregular and often rapid heartbeat. We provide comprehensive evaluation and personalized treatment plans to control symptoms and reduce stroke risk.
Medical information here is educational and not a substitute for professional care. If you think you’re having a medical emergency, call 911 or your local emergency number.
What it is
Atrial fibrillation is an irregular, often rapid heart rhythm starting in the atria. It disrupts normal blood flow and raises the risk of stroke.
Common symptoms
Palpitations, fatigue, shortness of breath, dizziness, chest discomfort, or feeling faint. Some people have no symptoms at all.
Good news
AFib can be managed. With treatment and lifestyle changes, many patients live active, healthy lives.
Symptoms
Atrial fibrillation (AFib) symptoms can vary widely—some people feel nothing at all, while others notice them right away. Common signs include a rapid or irregular heartbeat, fluttering in the chest, shortness of breath, fatigue, dizziness, or trouble exercising. Symptoms may come and go or be persistent, and even mild cases should be taken seriously since AFib can increase the risk of stroke and other heart problems.
Palpitations or fluttering
Rapid or irregular pulse
Shortness of breath
Fatigue or weakness
Dizziness or lightheadedness
Chest discomfort
Occasional fainting
Is It Urgent?
Call 911 or your local emergency number if an irregular heartbeat is accompanied by fainting, severe chest pain, trouble breathing, or occurs after a serious illness or injury.
If symptoms are mild or come and go, schedule an appointment—especially if you have heart disease, sleep apnea, thyroid problems, or a family history of arrhythmias.
CAuses and Risk Factors
Atrial fibrillation (AFib) often develops when changes in the heart disrupt its normal rhythm. Common causes include high blood pressure, heart disease, valve problems, or a history of heart surgery. Risk factors that raise the chance of AFib include age, obesity, diabetes, sleep apnea, and heavy alcohol use. Family history and certain chronic conditions can also play a role. While not all cases have a clear cause, knowing your risk factors can help with early detection and prevention.
High blood pressure
Heart disease or valve problems
Sleep apnea
Thyroid imbalance
Excess alcohol or stimulants
Age (more common after 60)
Family history of AFib
Prior heart surgery
Sometimes no clear cause (lone AFib)
How We Diagnose
AFib is diagnosed by checking your heart’s rhythm with an electrocardiogram (ECG) and, if needed, longer monitoring devices. Tests like an echocardiogram, blood work, or stress testing may also be used to find the cause and guide treatment.
ECG and Monitors
An ECG or wearable monitor confirms AFib and tracks your heart rhythm over time.
Echocardiogram
Ultrasound of the heart checks its structure, valves, and pumping strength.
Stress and Labs
Blood tests and treadmill testing help uncover triggers and related conditions.
Personalized Treatment Options
AFib treatment focuses on controlling rhythm, preventing stroke, and improving quality of life.
Lifestyle Changes
Limit alcohol, manage blood pressure, maintain healthy weight, and treat sleep apnea.
Medications
Medicines to control heart rate/rhythm and anticoagulants to reduce stroke risk.
Cardioversion
A safe, brief procedure using controlled electrical energy to restore normal rhythm.
Catheter Ablation
A minimally invasive procedure that isolates abnormal electrical signals in the atria.
Practical Tips for a Healthy, Active Heart
Living Well With AFib
Track your symptoms, take medications as prescribed, and never stop blood thinners without guidance. Many people with AFib safely return to the activities they enjoy.
Healthy Eating
Follow a balanced diet like DASH or Mediterranean-style.
Active Lifestyle
Get regular, moderate exercise as recommended.
Avoid Harmful Substances
Limit alcohol and avoid tobacco or vaping.
Heart Health Management
Control blood pressure, cholesterol, diabetes, and sleep.
