An arrhythmia (ay-RITH-mee-uh)
is an abnormal heart rhythm usually
caused by an electrical "short circuit" in the heart.
More to Know
The heart normally beats in a consistent pattern, but an arrhythmia can make it
beat too slowly, too quickly, or irregularly. This can cause the heart muscle's pumping
function to work erratically, which can lead to a variety of symptoms, including fatigue,
dizziness, and chest pain.
Arrhythmias can be temporary or permanent. They can be caused by several things,
but also can occur for no apparent reason. Congenital (present at birth) arrhythmias
sometimes are due to a birth
defect of the heart, but some happen even when the heart has formed normally.
Keep in Mind
Many arrhythmias don't require treatment; however, some can pose a health problem
and need to be evaluated and treated by a doctor.
