What is Atrial Fibrillation (AFib)?
Atrial fibrillation, also called AFib, is a heart condition that causes an irregular and often abnormally fast heart rate, that can lead to blood clots, stroke, heart failure and other heart-related complications.
In atrial fibrillation, the heart rate is irregular and can sometimes beat very fast. In some cases, it can be considerably higher than 100 beats a minute. You may be aware of noticeable heart palpitations, where your heart feels like it's pounding, fluttering, or beating irregularly.
Sometimes atrial fibrillation does not cause any symptoms and a person who has it is completely unaware that their heart rate is irregular.
Atrial Fibrillation is the most common heart rhythm disorder worldwide with more patients being diagnosed everyday.
