Atrial fibrillation

Atrial fibrillation (A-fib) is a type of irregular heartbeat that causes the atria, the upper chambers of the heart, to beat irregularly and often very quickly. The normal rhythm of the heart is controlled by electrical signals that travel through the heart's conduction system. In A-fib, these signals are disrupted, causing the atria to quiver or fibrillate. This can cause a number of symptoms, including:

• Palpitations or a fluttering feeling in the chest
• Lightheadedness or dizziness
• Fatigue
• Shortness of breath
• Chest pain

A-fib is a common condition, affecting millions of people around the world. It is more common in older adults, men, and people with certain medical conditions, such as high blood pressure, heart disease, and diabetes.

There are a number of different treatment options for A-fib, depending on the severity of the condition and the individual's overall health. Treatment options may include:

• Lifestyle changes, such as losing weight, exercising regularly, and quitting smoking
• Medications to control the heart rate and prevent blood clots
• Procedures to restore the normal rhythm of the heart, such as catheter ablation or surgery

A-fib is a serious medical condition that can increase the risk of stroke, heart failure, and other complications. However, with treatment, most people with A-fib can live long and healthy lives.

If you think you may have A-fib, it is important to see a doctor to get a diagnosis and discuss treatment options. Early diagnosis and treatment can help reduce the risk of complications.

Here are some additional facts about A-fib:

• A-fib is the most common type of irregular heartbeat.
• A-fib is a major risk factor for stroke.
• A-fib can increase the risk of heart failure, dementia, and other health problems.
• Treatment for A-fib can help improve symptoms and reduce the risk of complications.
