Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm, also known as an arrhythmia. During AFib, the hearts upper chambers, called the atria, beat chaotically and irregularly, out of sync with the lower heart chambers, called the ventricles. This irregular beating can lead to blood clots in the heart, increasing the risk of stroke, heart failure, and other heart-related complications.
AFib can be caused by problems with the hearts structure, heart diseases, and health problems such as congenital heart defects, sick sinus syndrome, and other heart-related issues. It can also be related to risk factors like advancing age, high blood pressure, obesity, European ancestry, diabetes, heart failure, and other conditions.
Symptoms of AFib may include irregular heartbeat, heart palpitations, lightheadedness, extreme fatigue, shortness of breath, and chest pain. However, some people with AFib may not experience any symptoms at all.
AFib can lead to serious complications such as blood clots, strokes, and heart failure. It is essential for individuals experiencing symptoms or at risk for AFib to seek medical attention for proper diagnosis and treatment. Treatment for AFib may include medications and other interventions to manage the condition and reduce the risk of complications.
In conclusion, AFib is a significant and common heart condition that requires attention and proper management to reduce the risk of serious complications. Understanding the causes, symptoms, and risk factors associated with AFib is crucial for early detection and effective treatment.
