What is a common cause of atrial fibrillation?

• A. Reduced physical activity
• B. Hypertension or heart disease
• C. Low cholesterol levels
• D. Genetic factors

Answer: (B)

Atrial fibrillation (AFib) is a type of irregular heartbeat that can lead to serious complications, including stroke. One of the most common causes of AFib is hypertension or heart disease. Elevated blood pressure can lead to changes in the heart's structure and electrical pathways, increasing the risk of developing this arrhythmia. Heart disease, which includes a wide range of conditions affecting the heart such as coronary artery disease and heart valve issues, can also contribute to the development of AFib. Both hypertension and heart disease can create an environment in the heart that promotes the chaotic electrical signals associated with atrial fibrillation. While reduced physical activity, low cholesterol levels, and genetic factors can influence overall heart health, they are considered less direct causes of AFib compared to the impacts of hypertension and heart disease, which have a more pronounced effect on the heart's electrical system and rhythm.
