Atrial Fibrillation

📖What is Atrial Fibrillation?

Atrial fibrillation is the most common type of irregular heart rhythm, or arrhythmia, in which the heart's upper chambers beat chaotically and out of coordination with the lower chambers. This irregular electrical activity prevents the atria from contracting effectively, which can allow blood to pool and form clots that increase the risk of stroke. The condition may occur in brief episodes that come and go, known as paroxysmal atrial fibrillation, or become persistent or permanent over time. Many people with atrial fibrillation notice palpitations or an irregular pulse, though some cases are entirely asymptomatic and discovered only during a routine examination or ECG. Management focuses both on controlling the heart rhythm or rate and on reducing stroke risk through blood-thinning medication.
