A
T
fl uttering heart can be a good
thing-a sign of new love, the
eff ects of an intense workout,
the thrill of a suspenseful
movie. Sometimes, changes in
heart rate happen out of the blue, which
can be unsettling.
Usually, experts say, disruptions in the
heart's steady beat, also called palpitations,
are nothing to worry about.
" In most people, palpitations don't
mean anything and are not harmful, but
that doesn't mean you don't feel them
and shouldn't pay attention to them.
Th ey are tricky, " says John Osborne,
MD, a cardiologist and American Heart
Association volunteer.
Occasionally, however, a random heart
rhythm indicates a serious problem-
for example, the irregular beating of
atrial fi brillation can lead to stroke or
heart failure.
Th ere are easy ways, fortunately, to
determine whether your heart skipping
a beat is the kind of thing to dismiss or
something to be concerned about.
Your Electric-Powered Heart
Th e heart is a four-chambered muscle
about the size of a fi st. It is powered by
electricity, rhythmically pumping blood
that carries nutrients and oxygen throughout
the body. Every day, the average heart
beats 100,000 times, pumping around
2,000 gallons of blood, the American Heart
Association says.
Amid the many millions of beats of our
hearts, some are bound to be irregular.
" Pretty much everybody at some point has
these little extra isolated beats, " Osborne
says. Most are not medical emergencies,
he adds. Aſt er a blip, the heart simply
resumes its regular beating as though
nothing was amiss.
