IS YOUR HEART

OFF BEAT?
Be aware of the symptoms of
atrial fibrillation BY LISA L. STAUFFER

T

hum-thump, thum-thump.
The heartbeat is a comforting,
steady sound. "When your
heart's four chambers
contract, they send blood flowing
throughout your body," says Niraj
Sharma, MD, a Gwinnett Medical
Group cardiac electrophysiologist.
"As an involuntary muscle, the heart
works 24/7. And like the body's other
involuntary muscles, these contractions
are triggered by electrical impulses
from certain nerves."
For most people, the electrical
signals work just fine. "But for others,"
Dr. Sharma says, "the electrical signals
may fire haphazardly, racing at times

or going too slow at other times.
This condition is known as atrial
fibrillation, or A-fib."
But would you know A-fib if you
had it? Consult your health care
provider if you experience any one
of these common A-fib symptoms
(even if they come and go):
* Having a pulse (heartbeat) that's
racing, pounding, fluttering, irregular
or too slow
* Feeling the heart beat
* Feeling confused, dizzy or
lightheaded
* Feeling fatigued
* Having shortness of breath or
losing your ability to exercise n
