Atrial Fibrillation

Atrial fibrillation, or A-Fib, happens when the upper chambers of the heart beat very rapidly (300-600 beats per minute) and irregularly. When your heart beats inefficiently, not enough blood is pumped to the rest of your body. This can cause shortness of breath, fatigue and a higher risk of stroke.

Depending on your medical history, having A-Fib can cause blood clots to form. If a clot forms in an upper chamber of your heart, the clot could come loose and cause a stroke. That’s why one of the most common treatments for A-Fib is taking a blood thinner, or anticoagulant, to prevent clots from forming. Other A-Fib treatments include:

• Atrial fibrillation ablation
• Cryoablation
• Devices like pacemakers, defibrillators and cardiac resynchronization devices
