Atrial Fibrillation: Understanding the Irregular Heartbeat
Atrial Fibrillation (AFib) is a common cardiac arrhythmia that affects millions of people worldwide. It is characterized by an irregular and often rapid heartbeat, which can lead to a range of health complications if left untreated. Understanding AFib, its causes, symptoms, and available treatments is essential for maintaining heart health. Causes and Mechanism: AFib occurs when the electrical signals that regulate the heart's rhythm become chaotic, causing the upper chambers of the heart (atria) to fibrillate or quiver instead of contracting properly. This disrupts the normal coordination between the atria and the lower chambers (ventricles), resulting in an irregular heartbeat. Several factors can contribute to the development of AFib, including: Age: The risk of AFib increases with age, especially in individuals over 65. Underlying Heart Conditions: Hypertension, coronary artery disease, heart valve disorders, and heart failure can predispose individuals to AFib. Lifestyle Facto...
