AFib is the most common type of cardiac arrhythmia, or abnormal heart rhythm. It is a heart rhythm disorder in which the smaller chambers (atria) of the heart contract too fast and irregularly when abnormal electrical impulses suddenly start firing in the atria. This reduces the heart’s efficiency and performance.

AFib can cause a wide variety of symptoms in most patients and can severely impact quality of life. However, some patients don’t feel any symptoms at all. Symptoms of AFib include heart palpitations, fatigue, difficulty exercising, shortness of breath, anxiety, chest pain and dizziness.^1,2

The cause of atrial fibrillation is not fully understood. Atrial fibrillation is more likely to occur in people with conditions such as high blood pressure, obesity, sleep apnea syndrome (stopping breathing during sleeping) and narrowing of the coronary arteries. It can be triggered in certain situations such as drinking too much alcohol or smoking.

AFib is diagnosed through an electrocardiogram (EKG), Holter monitor or stress test.

If left untreated, AFib may progress and get worse. It can also lead to other serious health conditions, such as stroke and heart failure.

Early treatment is essential for overcoming AFib. Treatment options include medications, cardioversion, and catheter ablation. Patients should consult with their physician on the appropriate treatment options and associated risks and benefits.

If you suspect you have AFib, it’s important to see a healthcare provider promptly. Early diagnosis and treatment can help manage the condition and reduce the risk of complications.
