Atrial fibrillation is an irregular and often rapid heart rate that can increase your risk of strokes, heart failure and other heart-related complications

During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness.

Episodes of atrial fibrillation may come and go, or you may develop atrial fibrillation that doesn't go away and may require treatment. Although atrial fibrillation itself usually isn't life-threatening, it is a serious medical condition that sometimes requires emergency treatment.

A major concern with atrial fibrillation is the potential to develop blood clots within the upper chambers of the heart. These blood clots forming in the heart may circulate to other organs and lead to blocked blood flow.

Symptoms

Some people with atrial fibrillation have no symptoms and are unaware of their condition until it's discovered during a physical examination. Those who do have atrial fibrillation symptoms may experience signs and symptoms.

Palpitations, which are sensations of a racing, uncomfortable, irregular heartbeat or a flip-flopping in your chest

• Weakness
• Reduced ability to exercise
• Fatigue
• Lightheadedness
• Dizziness
• Shortness of breath
• Chest pain.

Causes

Atrial fibrillation is an irregular and often rapid heart rate that occurs when the two upper chambers of your heart experience chaotic electrical signals. The result is a fast and irregular heart rhythm. The heart rate in atrial fibrillation may range from 100 to 175 beats a minute. The normal range for a heart rate is 60 to 100 beats a minute.

Your heart is made up of four chambers two upper chambers and two lower chambers. Within the upper right chamber of your heart is a group of cells called the sinus node? This is your heart's natural pacemaker. The sinus node produces the signal that normally starts each heartbeat.
