Atrial fibrillation is an irregular and often rapid heart beat. It is due to the chaotic and irregular beating of the two upper chambers of the heart. The irregular beating can come and go and the duration of the abnormal heart beat can be from seconds to hours to days. The heart rate can vary between 100 to 200 beats per minute.

What are the symptoms of atrial fibrillation?

The most common symptom of atrial fibrillation is that of a fast and irregular heart beat. It can also lead to giddiness, shortness of breathe, confusion, chest pain, and fatigue.

Abnormalities and damage to the heart can also cause atrial fibrillation and these would include heart attacks, high blood pressure, congenital heart problems, abnormal heart valve, post-heart surgery, lung diseases, infections, sleep apnea, over active thyroid and exposure to stimulants such as alcohol.

What problems can atrial fibrillation cause?

Atrial fibrillation results from the chaotic electrical beating of the upper chambers of the heart. As such, the chambers are not really contracting but merely quivering. This cause the blood in the upper chamber of the heart to stagnate and form tiny clots. These clots can then migrate up to the brain and cause strokes.

Atrial fibrillation also causes the heart to beat very fast. If the heart continues to beat very fast for a long period of time, the heart function can weaken and it will then lead to the development of heart failure.
