atrial fibrillation

Atrial fibrillation is an irregular heartbeat or arrhythmia. It can lead to stroke, heart failure and blood clots. Normally your heart contracts and relaxes to a regular beat. If you have atrial fibrillation, the upper chambers of the heart, called the atria, beat irregularly. This leads to ineffective movement of the blood. If a clot breaks off and enters your blood stream it can lodge in an artery leading to the brain. The result of this is a stroke.

What are the symptoms of atrial fibrillation?

  • Fatigue when exercising
  • Shortness of breath
  • Irregular or rapid heartbeat
  • Weakness or faintness
  • Sweating
  • Dizziness
  • Anxiety
  • Fluttering in the chest
  • Chest pain or pressure. This should be considered a medical emergency.
  • Some people have no symptoms at all.

 

 

 

 

 

 

There are five types of atrial fibrillation. Paroxysmal fibrillation occurs when the heart returns to a normal beat on its own within a week. If it lasts for longer than a week, it is considered persistent. Long standing fibrillation will continue for more than a year and if it is permanent, it lasts indefinitely. There is also a type of fibrillation called nonvalvular which is not caused by a problem with the heart valves.

Atrial fibrillation is usually suspected during a routine doctor’s visit. To check, an ECG can be performed. Monitoring can also be done for 24 to 48 hours. This is done by wearing a small device which connects electrodes to your chest.

How can you reduce your risk of stroke caused by atrial fibrillation?

  • Eat a diet that is healthy for your heart. Reduce your use of salt, saturated and trans fats and cholesterol.
  • Keep your blood pressure at a normal level.
  • Stay active. Keep your heart healthy with regular physical activity.
  • Avoid alcohol and smoking.
  • Maintain a weight that is healthy for your body frame.
