Atrial fibrillation (AFib) is the most common type of heart arrhythmia, defined by an irregular and typically rapid pulse rate that originates in the heart’s upper chambers, or atria. Instead of contracting in a coordinated manner, the atria fibrillate or quiver, resulting in inefficient blood pumping and possible blood pooling within the heart. AFib raises the risk of blood clots, strokes, heart failure, and other cardiovascular issues.

Atrial fibrillation can be caused by a variety of cardiac problems, including hypertension, coronary artery disease, heart valve disease, heart failure, congenital heart defects, or prior heart surgery. Other risk factors for AFib include advanced age, obesity, diabetes, sleep apnea, heavy alcohol consumption, smoking, and a family history of the disorder. Furthermore, certain medical problems, like as hyperthyroidism, lung disease, and acute illness or infection, might cause AFib episodes.

Atrial fibrillation symptoms can range from mild to severe and include palpitations (rapid or irregular heartbeat), fatigue, shortness of breath, dizziness or lightheadedness, chest pain or discomfort, and fainting (syncope). Some people with AFib may have no symptoms and only become aware of the illness during standard medical exams or diagnostic procedures.

Atrial fibrillation is often diagnosed using a medical history, physical examination, and diagnostic tests such as electrocardiogram (ECG or EKG), Holter monitoring, event monitoring, echocardiography, or cardiac MRI to assess heart rhythm and structure. Early detection and precise diagnosis of AFib are critical for commencing effective therapy and minimizing the risk of complications.

The goal of atrial fibrillation treatment is to reduce heart rate, restore normal heart rhythm, avoid blood clots and strokes, and manage underlying risk factors and comorbidities. To lower the risk of blood clots, AFib treatment options may include antiarrhythmic medicines, beta-blockers, calcium channel blockers, and anticoagulants (blood thinners). In some circumstances, cardioversion (electrical or chemical) or catheter ablation operations may be required to restore normal heart rhythm.

Lifestyle changes can also help manage atrial fibrillation and lower the risk of problems. These may include keeping a healthy weight, eating a heart-healthy diet low in sodium and saturated fats, exercising regularly, stopping smoking, limiting alcohol use, managing stress, and controlling underlying medical disorders such as hypertension and diabetes.

In conclusion, atrial fibrillation is a common cardiac rhythm condition defined by an irregular and typically rapid heart rate that originates in the upper chambers of the heart. While AFib increases the risk of major cardiovascular consequences, early detection, timely medication, and lifestyle changes can help people manage the illness and lower their risk of complications.
