Irregular Heartbeat
------------------------------------------------------------------------------
QUESTION: I can tell that my heart doesn't always beat on time, but seems to
jump once in a while. I think you doctors have a special name for that, but I
would like to know why it happens?
------------------------------------------------------------------------------
ANSWER: An irregular heartbeat is called an "arrhythmia", and there are many
kinds, bearing different names and having different causes. Some are quite
common, like a skipped beat or "extrasystole," and do not have serious
implications. Others require study for a precise diagnosis.
Your heartbeat is affected by many factors. Body temperature, exercise,
emotional stress are just a few. Even things you may eat can cause your heart
rate to change. Stimulants like the caffeine in coffee, tea, chocolate, and
cola often have that effect. Internally, impulses and signals which travel
along nerves from the spinal cord and brain to the heart can affect the
rhythm, pace, and power of the heartbeat.
If your heart is healthy, it speeds up and slows down daily to meet the
needs of your body. There are, however, several heart conditions that may
cause abnormal arrhythmias.
A heart attack, technically called myocardial infarction, often causes
damage to heart tissue, and may lead to arrhythmias. An irregular heartbeat
is also common in patients with congestive heart failure--when the heart is
not strong and does not pump enough blood through the body. Other heart
diseases can also cause arrhythmias.
If you think you are having problems with arrhythmias, see a doctor. A
simple test like a cardiogram will enable your physician to determine whether
the arrhythmias you are having are commonplace, or whether they require
treatment.
