Atrial fibrillation (AFib) is a common heart rhythm disorder affecting millions worldwide. Understanding the causes and early signs of AFib is crucial for timely detection, intervention, and effective management. The subtle yet vital signs that indicate its presence can be mistaken as nothing serious or a symptom of some other health condition. By unraveling the mysteries behind AFib, it is essential to empower oneself with the knowledge that can lead to proactive heart health management and improved quality of life. Causes of atrial fibrillation Age As one grows old, the risk of developing atrial fibrillation increases. The wear and tear on the heart’s electrical system over time can disrupt its normal rhythm and lead to AFib. Additionally, age-related conditions such as high blood pressure, heart disease, and underlying structural abnormalities can further predispose individuals to AFib. High blood pressure Hypertension, or high blood pressure, is a significant risk factor for atrial fibrillation. Persistent elevation in blood pressure can damage the heart’s electrical system and promote irregular heartbeats. Managing and controlling blood pressure through lifestyle modifications and appropriate healthcare interventions is crucial in reducing the risk of developing AFib. Heart conditions and diseases Various heart conditions and diseases can contribute to the development of atrial fibrillation.
