Atrial Fibrillation
An irregular and often rapid heart rhythm that increases the risk of stroke and heart failure.
Overview
Atrial fibrillation (AFib) is the most common type of heart arrhythmia, characterized by an irregular and often rapid heartbeat. The upper chambers of the heart (atria) quiver instead of beating effectively, which can cause blood to pool and form clots — significantly increasing stroke risk. AFib can be episodic (paroxysmal) or persistent, and is more common with age, high blood pressure, and other heart conditions.

Diagnosis
Diagnosis typically involves clinical evaluation, medical history, blood tests, and appropriate imaging studies. A healthcare provider will assess symptoms, order relevant laboratory work, and may refer to a specialist for confirmation.
Treatments
Treatment depends on the underlying cause and severity. Options may include medication, lifestyle modifications (diet, exercise, stress management), and ongoing monitoring. Always work with a qualified healthcare provider to develop an appropriate treatment plan.
