Atrial Fibrillation: Definition and Explanation
Introduction
Atrial fibrillation (AF) is a common type of heart rhythm disorder (arrhythmia) that causes an irregular and often rapid heartbeat. This occurs when the upper chambers of the heart (atria) beat chaotically and out of sync with the lower chambers (ventricles).
Why is AF Important?
AF can lead to several health complications, including:
- Blood clots forming in the heart, increasing the risk of stroke.
- Inefficient blood pumping, leading to heart failure.
- Increased likelihood of other heart-related complications.
Types of Atrial Fibrillation
- Paroxysmal AF : Episodes start suddenly and stop on their own within 7 days.
- Persistent AF : Lasts longer than 7 days and may require treatment to restore normal rhythm.
- Long-standing persistent AF : Persists for over a year, often requiring medical intervention.
- Permanent AF : Normal rhythm can't be restored or is not attempted.
Symptoms of AF
- Palpitations (rapid, fluttering heartbeat)
- Shortness of breath
- Dizziness or lightheadedness
- Fatigue and weakness
- Chest discomfort or pain
Causes of AF
AF can be triggered by various conditions, including:
- High blood pressure (hypertension)
- Coronary artery disease
- Heart valve problems
- Hyperthyroidism
- Excessive alcohol consumption
- Sleep apnea
Conclusion
Atrial fibrillation is a serious but manageable condition. Early diagnosis and appropriate treatment can reduce complications and improve quality of life. If you suspect AF, consult a cardiologist for a proper evaluation.

If you or your loved ones experience any of these symptoms, you should consult a doctor in time. Remember that self-medication can be dangerous, and timely diagnosis will preserve the quality and life expectancy.
The heart is an organ that does not know how to "keep silent" if something goes wrong. Chest pain, shortness of breath, swelling, dizziness, and rhythm disturbances are the symptoms that require our attention. The best prevention of heart disease is careful attention to your health, regular checkups with a doctor, and a healthy lifestyle. Take care of your heart, and it will serve you for many years!
