Atrial fibrillation (AF or A-fib) is a rare heart rhythm (arrhythmia) characterized by rapid and irregular beating of the cardiac chambers. It usually starts as short periods of abnormal lungs, becoming longer or longer over time. It can also develop as other arrhythmia alternatives such as atutter flutter that eventually transforms into AF. [12] Often episodes have no symptoms. At times there may be heart problems, fainting energy, dizziness, dizziness, or chest pains. The disease is associated with an increased risk of heart failure, dementia and stroke. It is a type of supraventricular tachycardia. High blood pressure and coronary heart disease are among the most common risk factors for AF. Other risk factors associated with the heart include heart failure, coronary artery disease, cardiomyopathy, and congenital heart disease. In developing countries, coronary heart disease is more likely to occur due to rheumatic fever.
