Atrial fibrillation is a common disorder affecting approximately 250,000 Canadians. The incidence of atrial fibrillation increases with age and doubles every decade after the age of 55. Yet many Canadians, particularly the elderly who are at highest risk, are unaware of the damage it can do to their heart. Atrial fibrillation is a type of heart arrhythmia that causes an irregular or rapid heart beat. If left untreated, atrial fibrillation can weaken the heart which can lead to serious complications including heart failure and stroke.
