What is AF?

AF, or atrial fibrillation, is a heart rhythm disorder that causes the heart to beat irregularly. The heart's normal rhythm is controlled by the sinus node, which is located in the right atrium. When the sinus node is not working properly, electrical signals can fire from other parts of the heart, causing the heart to beat too fast, too slowly, or irregularly. AF is the most common type of arrhythmia, and it affects millions of people worldwide.

There are two main types of AF, paroxysmal and persistent:

• Paroxysmal AF is the most common type. It comes and goes, and can last for a few minutes, hours, or days.
• Persistent AF is a more serious type that lasts for more than 7 days. It can be very difficult to treat, and it can lead to serious complications.

AF can cause a variety of symptoms, including:

• Palpitations (a feeling of a fluttering or racing heart)
• Chest pain
• Shortness of breath
• Lightheadedness or dizziness
• Fatigue
• Confusion
• Stroke

The good news is that AF is usually treatable. There are a variety of medications that can be used to control the heart rate and rhythm, and some people may need surgery or other procedures. Lifestyle changes, such as losing weight, eating a healthy diet, and exercising regularly, can also help to reduce the risk of developing AF.

If you think you may have AF, it's important to see a doctor right away. Early diagnosis and treatment can help to prevent serious complications.
