Atrial Fibrillation

What is atrial fibrillation?

Atrial fibrillation (AFib) is a common type of arrhythmia, an irregular heart rhythm. A healthy heart beats in a predictable rhythm as its electrical signals follow a regular pathway through the upper chambers (atria) and lower chambers (ventricles).

If you have AFib, these electrical signals become disorganized, causing the atria to quiver (or “fibrillate”) rather than contract effectively. Your heart may beat too fast, too slow, or irregularly, which can make your blood flow through the heart less efficiently.

AFib is more common in older adults and those with underlying heart disease, but it can occur in anyone.

What are the symptoms of atrial fibrillation?

Some people with AFib have no symptoms at all and only discover it during a routine exam. However, when symptoms appear, they frequently include:

• Heart palpitations (a fluttering, pounding, or racing heartbeat)
• Shortness of breath
• Fatigue or weakness
• Dizziness or lightheadedness
• Chest discomfort or pain
• Reduced ability to exercise

Because AFib affects how your heart pumps blood, it can lead to complications such as heart failure or stroke. In fact, more than 20% of annual strokes relate to AFib, and women are at higher risk of severe outcomes.

Talk to Dr. Ortega if you experience any AFib symptoms.

How is atrial fibrillation treated?

Dr. Ortega listens carefully to your symptoms and investigates the cause of your irregular heartbeat. Treatment for AFib aims to regulate your heartbeat and protect you from blood clots.

Your care plan may include:

Medications

Medications such as beta-blockers, calcium channel blockers, or digoxin help slow the heart rate, allowing the ventricles to fill more completely and improving heart function. Dr. Ortega may also prescribe antiarrhythmic medications to restore your heart’s normal rhythm.

Stroke prevention

Because of the risk of clotting, Dr. Ortega may recommend that you take anticoagulant (blood-thinning) medications, such as warfarin or newer agents like apixaban, rivaroxaban, or dabigatran.

Lifestyle modifications

Managing underlying conditions and improving your heart health are essential. Dr. Ortega can recommend solutions to help you:

• Treat high blood pressure, diabetes, and sleep apnea
• Limit alcohol and caffeine
• Maintain a healthy weight
• Find an exercise you enjoy
• Avoid smoking

Attend your follow-up appointments, stick with any prescribed medications, and maintain a healthy lifestyle. Dr. Ortega can help you manage AFib and live the life you deserve. To schedule your consultation, call the office or book conveniently online today.
