About Atrial Fibrillation

 



What is atrial fibrillation?
Atrial fibrillation, also known as A-fib, is a fairly common condition that causes the upper chambers of the heart (atria) to beat quickly and in an uncontrolled manner (fibrillation). This irregular and often rapid heart rate often causes poor blood flow to the body and an irregular pulse.

What are the symptoms of atrial fibrillation?
Symptoms include:

  • Heart palpitations (irregular or rapid heartbeat)
  • Shortness of breath
  • Irregular pulse
  • Dizziness
  • Chest pain
  • Tiredness and weakness

Sometimes there is a sensation of fluttering in the chest. However, for many, there are no noticeable symptoms.

A-fib can be occasional (symptoms come and go over minutes or hours) or chronic (symptoms do not go away without treatment).

What puts you at risk?
Often there is no obvious reason for developing A-fib. However, there are some factors that we know do cause it:

  • Excessive alcohol use
  • Physical stress
  • Medications that stimulate the heart
  • Heart surgery
  • Coronary artery disease, heart failure, heart valve disease and a history of heart attacks
  • Pericarditis (inflammation of the sac around the heart)

Take the online AFib risk assessment to determine your risk of atrial fibrillation.
