Atrial Fibrillation

What is Atrial Fibrillation?

Normally, your hear contracts and relaxes to a regular beat. Your heart beats because certain cells in your heart make electrical signals that cause the heart to contract and pump blood. This electrical signal shows up on a electrocardiogram, or ECG machine.

Your doctor can use this machine to find out if the electrical signals are normal.

In atrial fibrillation, part of the heart doesn't beat the way it should. Instead of beating in a regular, normal pattern, part of the heart beats irregularly and too fast. It's important for the heart to pump properly because that's how your body gets the oxygen and food it needs.

You can live with atrial fibrillation, but it can cause stroke or more serious heart rhythm disturbances. You'll need a doctor to help you control the problem.

How do I know I have Atrial Fibrillation?

• Irregular heart beat
• Heart palpitations or rapid thumping inside the chest
• Shortness of breath
• Get tired more easily when exercising

What can correct it?

• Sometimes atrial fibrillation can be corrected with an electric shock. This shock may change the beat of your heart back to normal.
• You may take medicine, such as digitalis. It can return your heart rate to a normal rhythm. Ask you doctor, nurse or pharmacist about this drug.

How can I Learn More?

• Talk to your doctor, nurse or health care professional.
• If you have heart disease, members of your family also may be at higher risk. It's very important for them to make changes now to lower their risk.
