What Is Atrial Fibrillation?
Atrial fibrillation (AFib) is a common heart condition characterized by an irregular and often rapid heartbeat. This condition occurs when the electrical signals in the heart become disorganized, leading to ineffective contractions of the heart’s upper chambers, known as the atria. As a result, blood may not be pumped efficiently into the lower chambers (ventricles), which can increase the risk of blood clots, stroke, and other heart-related complications.
Understanding the Heart’s Electrical System
To grasp the concept of atrial fibrillation, it’s essential to understand how the heart’s electrical system works. The heart has a natural pacemaker called the sinoatrial (SA) node, which generates electrical impulses that regulate the heartbeat. In AFib, these impulses become chaotic, causing the atria to quiver instead of contracting effectively. This disorganized electrical activity can lead to a heart rate that is either too fast or too slow.
Types of Atrial Fibrillation
Atrial fibrillation can be classified into several types:
- Paroxysmal AFib: This type comes and goes, with episodes lasting from a few minutes to several hours. It often resolves on its own.
- Persistent AFib: In this case, the irregular heartbeat lasts longer than seven days and may require medical intervention to restore a normal rhythm.
- Permanent AFib: This type is ongoing and cannot be corrected. Management focuses on controlling the heart rate and reducing stroke risk.
Causes of Atrial Fibrillation
Several factors can contribute to the development of atrial fibrillation, including:
- Heart conditions: High blood pressure, heart valve disease, and coronary artery disease can increase the risk.
- Other medical conditions: Conditions such as hyperthyroidism, diabetes, and sleep apnea may also play a role.
- Lifestyle factors: Excessive alcohol consumption, smoking, and obesity can contribute to AFib.
Atrial Fibrillation Symptoms
