About Atrial Fibrillation

Atrial brillation is a common heart rhythm problem.

It affects more than 2 million people in North America.

It is more common in older age and is found in 10%

of people over 80 years old. It is a common cause of

strokes. About 15% of all strokes are caused by atrial

brillation.

The elderly or those with high blood pressure, diabetes

or heart disease are more likely to get a stroke if they

have atrial brillation.

Atrial brillation is a rhythm problem that can last from

a few minutes, too days, weeks or even years. Atrial

brillation can cause blood clots in the upper chambers

of the heart (the atria). These clots can break off and

ow to the brain causing a stroke.

The use of blood thinners, such as warfarin, can

lower the risk of a stroke in patients with atrial

brillation.

A doctor can conrm if atrial brillation is present

by performing an ECG. Sometimes Atrial brillation

is present incidentally. Therefore, a doctor may not

see it on regularly scheduled visits.

One method of detecting atrial brillation is by

means of palpitations during blood pressure

measurement. This method is not very reliable.

Failure to detect Ab may in the end lead to the

occurrence of a stroke; whereas early detection may

lead to early treatment that can signicantly reduce

the chances of a stroke.
