What Causes Atrial Fibrillation?
Atrial fibrillation (AF) occurs when the electrical
signals traveling through the heart are conducted abnormally and become
disorganized and very rapid.
This is the result of damage to the heart’s
electrical system. This damage is most often the result of other conditions,
such as
coronary
artery disease or
high
blood pressure, that affect the health of the heart. Sometimes, the cause
of AF is unknown.
