Atrial fibrillation, often abbreviated as AFib, is the most common type of heart rhythm disorder (arrhythmia). In a healthy heart, electrical signals coordinate the beating of the upper chambers (atria) and lower chambers (ventricles). With AFib, these electrical signals become chaotic and disorganized, causing the atria to quiver irregularly instead of contracting effectively. This then causes the bottom chambers of the heart to contract fast and irregular. We specialize in diagnosing and treating AFib to safeguard your heart health and reduce your risk of complications.

Understanding the Heart’s Rhythm:

The top chambers of the heart (atria) squeeze first, specifically initiated by an area in the right atrium called the sinus node. This electrical impulse travels to the bottom chambers of the heart (ventricles), which then contract and pump blood to the rest of your body. In a normal rhythm, these chambers work together in a coordinated sequence, directed by electrical signals.

What Happens in Atrial Fibrillation?

With AFib, the electrical signals in the atria become disorganized, causing them to quiver instead of contract effectively. This quivering can disrupt the normal flow of blood from the atria to the ventricles, potentially leading to complications including symptoms, strokes, and congestive heart failure.

Symptoms of Atrial Fibrillation:

AFib symptoms can vary from person to person. Some individuals may not experience any noticeable symptoms, while others might have:

• Palpitations: A fluttering, racing, or skipping heartbeat sensation.
• Shortness of breath: This can occur at rest or with exertion.
• Fatigue and weakness: You may feel unusually tired, even with minimal activity.
• Chest discomfort: You might experience pressure, tightness, or pain in your chest.
• Lightheadedness or dizziness: This can be a sign of reduced blood flow to the brain.

Early Detection is Key:

Due to the often-silent nature of AFib, regular screenings are crucial, especially for individuals with risk factors. Early detection allows for prompt intervention and helps prevent complications. We can assess you for AFib with several diagnostic tools.

Risk Factors for Atrial Fibrillation:

Several factors increase your risk of developing AFib, including:

• High blood pressure: Uncontrolled hypertension puts extra strain on the heart and can damage heart tissue, increasing the risk of AFib.
• Coronary artery disease (CAD): Blocked or narrowed arteries can contribute to AFib.
• Heart failure: A weakened heart muscle can disrupt electrical signals, leading to AFib.
• Heart valve problems: Diseased heart valves, especially mitral valve stenosis or aortic stenosis, can increase the risk of AFib.
• Sleep apnea: This sleep disorder can disrupt oxygen levels in the blood, potentially contributing to AFib.
• Age: The risk of AFib naturally increases with age.
• Family history: Having a close relative with AFib raises your risk.
• Certain medical conditions: Thyroid disorders, obesity, and diabetes can also contribute to AFib risk.

Complications of Atrial Fibrillation:

The main concern with AFib is the increased risk of stroke. When the atria quiver ineffectively, blood can pool and form clots. If a clot breaks free and travels to the brain, it can block an artery and cause a stroke. We take a proactive approach to prevent stroke in AFib patients.

Treatment Options for Atrial Fibrillation:

Treatment for AFib focuses on two main goals:

1. Controlling the heart rate and rhythm: This can be achieved with medications or minimally invasive procedures like catheter ablation.
2. Preventing blood clots that cause strokes: Blood thinners like warfarin or newer medications called novel oral anticoagulants (NOACs) are often prescribed to reduce the risk of stroke. In patients who cannot tolerate these blood thinners, we offer the WATCHMAN procedure as a safe alternative.

The specific treatment approach will depend on the severity of your AFib, your overall health, and your risk factors for stroke. Here at Cardiac Specialists, we will work with you to create a personalized treatment plan to manage your AFib and safeguard your heart health.

Living Well with Atrial Fibrillation:

With proper diagnosis and treatment, most people with AFib can live long and healthy lives. By managing risk factors, following your treatment plan, and attending regular checkups, you can reduce your risk of complications and improve your quality of life.
