I48: Atrial fibrillation and flutter
I48.2: Chronic atrial fibrillation
Chronic atrial fibrillation is a heart condition characterized by irregular and often rapid heart rate. This condition occurs when the two upper chambers of the heart, the atria, beat unpredictably and out of coordination with the two lower chambers of the heart, the ventricles. As a result, the heart's efficiency in pumping blood is reduced. The primary symptoms include heart palpitations, shortness of breath, fatigue, and weakness. Chronic atrial fibrillation refers to the long-term presence of this condition, with episodes lasting for a week or more, or persisting until treated. Its causes include high blood pressure, heart attack, lung diseases, or abnormal heart valves. It's important to note that some people with this condition may not experience any symptoms, but they are still at a higher risk of stroke due to blood clots which can form in the heart and circulate to the brain.
