What is Atrial Fibrillation (AF)?

Atrial Fibrillation (AF) is a common heart condition that affects millions of people worldwide. It is a type of arrhythmia, which means that the heart beats irregularly or at an abnormal rate. In AF, the heart's upper chambers (atria) quiver instead of contracting effectively, leading to an irregular and often rapid heartbeat.

What causes Atrial Fibrillation?

There are several factors that can contribute to the development of AF. These include:

  • High blood pressure: Hypertension is a major risk factor for AF.
  • Heart diseases: Conditions such as coronary artery disease, heart valve problems, and heart failure can increase the risk of AF.
  • Age: The risk of AF increases with age, especially after the age of 60.
  • Obesity: Being overweight or obese can put extra strain on the heart and increase the likelihood of AF.
  • Family history: If you have a family member with AF, you may be more likely to develop the condition.

What are the symptoms of Atrial Fibrillation?

Some people with AF may not experience any symptoms and may only discover their condition during a routine medical check-up. However, others may experience the following symptoms:

  • Irregular heartbeat: The most common symptom of AF is a rapid and irregular heartbeat.
  • Heart palpitations: You may feel like your heart is fluttering, pounding, or racing in your chest.
  • Shortness of breath: AF can make it difficult to breathe, especially during physical activity.
  • Fatigue: Feeling tired or lacking energy is another common symptom of AF.
  • Dizziness or lightheadedness: Some people with AF may experience dizziness or fainting spells.

How is Atrial Fibrillation diagnosed and treated?

If you suspect you have AF or are experiencing any of the symptoms mentioned above, it is important to seek medical attention. A healthcare professional will perform a thorough evaluation, which may include:

  • Physical examination: Your doctor will listen to your heart and check for any irregularities.
  • Electrocardiogram (ECG): This test records the electrical activity of your heart and can help diagnose AF.
  • Additional tests: In some cases, additional tests such as echocardiogram, stress test, or Holter monitor may be recommended.

Treatment for AF aims to control the heart rate, restore normal heart rhythm, and prevent blood clots. The specific treatment plan will depend on various factors, including the severity of symptoms, underlying health conditions, and individual preferences. Treatment options may include:

  • Medications: Antiarrhythmic drugs and anticoagulants are commonly prescribed to manage AF.
  • Cardioversion: This procedure uses electrical shocks or medications to restore normal heart rhythm.
  • Ablation: Ablation involves the use of catheters to destroy or scar the tissue causing the abnormal heart rhythm.
  • Implantable devices: In some cases, a pacemaker or implantable cardioverter-defibrillator (ICD) may be recommended.

It is important to note that AF is a chronic condition that requires ongoing management and regular follow-up with a healthcare professional. By working closely with your doctor and making necessary lifestyle changes, you can effectively manage AF and reduce the risk of complications.
