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 too fast. In AF, the atria, which are the two upper chambers of the heart, beat irregularly and faster than the ventricles, which are the two lower chambers of the heart. This can cause a number of symptoms and can also lead to more serious complications.

​

Symptoms of AF can include:

​

• Irregular or rapid heartbeat

• Palpitations (feeling like your heart is racing or fluttering)

• Shortness of breath

• Fatigue

• Dizziness or lightheadedness

• Chest pain or discomfort

• ​

It is important to note that some people with AF may not experience any symptoms at all. However, even without symptoms, AF can still increase the risk of more serious complications, such as stroke, heart failure, or other heart-related problems.

​

The causes of AF can vary and may include:

​

• Age (AF is more common in older adults)

• High blood pressure

• Heart disease, such as coronary artery disease or valve problems

• Obesity

• Sleep apnea

• Hyperthyroidism (overactive thyroid)

• Alcohol or drug use

• ​

If you suspect that you may have AF, it is important to see your doctor for an evaluation. Your doctor may perform an electrocardiogram (ECG or EKG) to diagnose AF and determine the underlying cause. They may also order additional tests or imaging studies to evaluate the structure and function of your heart.

​

Treatment for AF may include medications, lifestyle changes, or medical procedures, depending on the severity and underlying cause of the condition. Medications may be used to control the heart rate, rhythm, or blood thinners to prevent blood clots and reduce the risk of stroke. Lifestyle changes, such as quitting smoking, losing weight, or reducing alcohol intake, may also help to manage AF symptoms and reduce the risk of complications. In some cases, medical procedures such as cardioversion, ablation, or surgery may be recommended to restore normal heart rhythm or treat underlying heart conditions.

​

In summary, atrial fibrillation is a common heart condition that can cause a number of symptoms and increase the risk of serious complications. If you suspect that you may have AF, it is important to see your doctor for an evaluation and discuss appropriate treatment options. With proper management, many people with AF can live full and active lives.
