Everything You Need to Know About AFib

By Devin Bevis

One health concern that often arises in seniors is atrial fibrillation, commonly known as AFib. This irregular heart rhythm condition or arrhythmia, can have significant implications for seniors' health and well-being. Let's dive into everything seniors and their families need to know about AFib, from its causes to treatment options.

What Is AFib?

Atrial fibrillation is a heart rhythm disorder characterized by irregular and often rapid beating of the heart. More specifically, this medical condition refers to rapid beating in the heart's upper chambers, known as the atria. Instead of beating in a regular, coordinated rhythm, the atria quiver or fibrillate, leading to an irregular heartbeat.

This irregularity can disrupt normal blood flow through the heart. As a result, the upper chambers cannot pump enough blood out, causing it to pool. If left untreated, AFib can increase the risk of blood clots, heart failure, and strokes.

Risk Factors & Causes of AFib

AFib is more commonly observed in seniors. This due to the natural aging process, which can lead to changes in the heart's structure and electrical system. However, other factors can contribute to its development, including the following:

  1. High Blood Pressure: Seniors with uncontrolled high blood pressure are at a higher risk of developing AFib.
  2. Heart Disease: Heart conditions, such as coronary artery disease, heart valve problems, and previous heart surgeries, can increase the risk of AFib.
  3. Obesity: Being overweight or obese can strain the heart and increase the risk of heart rhythm disorders.
  4. Diabetes: Diabetes is associated with an increased risk of various cardiovascular issues, including AFib.
  5. Sleep Apnea: Seniors with untreated sleep apnea are at higher risk of AFib because it puts more strain on the heart.
  6. Alcohol and Caffeine: Excessive consumption of alcohol and caffeine can trigger AFib episodes.
  7. Lifestyle Factors: Smoking, a sedentary lifestyle, and stress can also contribute to the development of AFib.
  8. Thyroid Disease: Thyroid disease and related disorders can increase the risk of irregular heartbeat.

Recognizing the Symptoms

AFib symptoms can vary widely among individuals. Some seniors may not have any symptoms at all. And others may only experience symptoms periodically. And some older adults will experience AFib symptoms permanently.

Some of the most common symptoms include:

  • Rapid, fluttering, or pounding heartbeat (heart palpitations)
  • Shortness of breath
  • Fatigue
  • Dizziness or lightheadedness
  • Chest discomfort or pain
  • Weakness

When senior's don't feel any symptoms of Afib, it is referred to as "silent AFib." Silent AFib can still pose serious health risks. Regular check-ups and screenings are crucial for early detection, especially for seniors who are at higher risk.

When to See a Doctor

If you or a loved one notices signs of AFib, don't panic! AFib usually isn't life-threatening, but you and your loved ones should still take it seriously. It requires proper treatment to prevent strokes and other cardiovascular problems.

If a loved one experiences chest pain, they should see a doctor immediately. This could be a sign of a more serious heart condition, including a heart attack.

Diagnosis and Treatment Options


To diagnose AFib, a doctor typically performs a medical history assessment, physical examination, and diagnostic tests. Such tests may include electrocardiograms (ECGs or EKGs) to monitor the heart's electrical activity.

In some cases, doctors may ask people with AFib to wear a heart monitoring device that can track heart beats 24/7. This can give doctors a better idea of how your heart is performing, especially if you have AFib episodes.


AFib treatment options aim to manage symptoms, prevent complications, and reduce the risk of stroke. The appropriate treatment plan will depend on factors such as the severity of symptoms, underlying health conditions, and the senior's preferences.

Here are some common AFib treatments:

  1. Medications: Doctors may prescribe medications to control heart rate, rhythm, and reduce the risk of blood clots. They may also prescribe blood thinners (anticoagulants) to prevent strokes.
  2. Cardioversion: This procedure involves delivering an electric shock to the heart to restore its normal rhythm.
  3. Ablation: Catheter ablation is a minimally invasive procedure that targets and destroys the areas of the heart causing abnormal rhythms.
  4. Pacemaker: In some cases, a doctor will recommend a pacemaker to regulate the heart's rhythm.
  5. MAZE Procedure: This is a type of surgery that causes scar tissue to develop on the heart. The scar tissue can actually help create a pattern to guide electrical heart signals.
  6. Lifestyle Changes: Seniors help manage AFib by adopting heart-healthy habits. This includes maintaining a balanced diet, engaging in regular exercise, managing stress, and avoiding triggers, such as excessive alcohol and caffeine.

Caring for Seniors with AFib

For people with atrial fibrillation, having a strong support system from their families can make a significant difference in their well-being. Here's how families can provide effective support:

  1. Education: Learn about AFib together as a family. Understand the condition, its symptoms, treatment options, and potential complications. The more you know, the more prepared you will be!
  2. Medication Management: Assist seniors in keeping track of their medications and ensure they take them as prescribed.
  3. Doctor's Visits: Accompany your loved one to medical appointments, take notes, and ask questions to ensure everyone understands the treatment plan.
  4. Healthy Lifestyle: Encourage and participate in adopting a heart-healthy lifestyle. Plan and prepare nutritious meals, engage in physical activities together, and find stress-reduction techniques that work for everyone.
  5. Emotional Support: AFib can be overwhelming, and seniors may experience anxiety or depression. Be there to listen, provide reassurance, and encourage open communication.
  6. Emergency Plan: Develop a clear plan for handling AFib-related emergencies, including knowing when to seek immediate medical attention.

Atrial fibrillation is a common heart rhythm disorder that disproportionately affects seniors. Understanding its causes, symptoms, and treatment options is crucial for both seniors and their families. By working together and providing the necessary support, families can help seniors effectively manage AFib, reduce complications, and lead healthier lives.
