What is Atrial Fibrillation?
Atrial Fibrillation (AF), or Arrhythmia is a common cardiac rhythm condition that is seen increasingly with age (especially over age 60). The normal electrical trigger for the heart beat in the top chambers (atria) of the heart becomes disrupted by rapid, erratic electrical signals that result in a quivering motion of the top chambers rather than the regular pumping action.
AF leads to an increased risk of a blood clot forming in the top chambers of the heart (in particular, the left atria) which, if it dislodges and travels to the brain, results in a stroke. See more on our AF Centre of Excellence page.
