Having palpitations means that you are unusually aware of your
heartbeat. The experience of palpitations is often described differently by
different people. Some people report a vague "fluttering" in their chests or the
feeling of a "skipped beat." Others note a "pounding sensation" or feel
that the heart is "jumping out of my chest." Palpitations are rarely
What are the different types of palpitations?
The pattern of the palpitations can be very helpful in determining
the type of arrhythmia that caused them. If you see a doctor about your
palpitations, it is very helpful if you can demonstrate the rhythm and speed of
the palpitations by tapping your fingers on a desk or table. This can help your
doctor figure out whether the palpitations were the result of an arrhythmia and
in some cases may allow a relatively accurate diagnosis as to the specific
arrhythmia that caused the palpitations.
Your doctor will likely not diagnose an arrhythmia based on
your demonstration. But it can be a very helpful start if you are not experiencing
arrhythmia while you are in your doctor's office (which means your doctor will
be unable to record the arrhythmia on an EKG during the visit).
How do palpitations cause chest discomfort?
Some people experience rapid heart rates not as palpitations but
rather as chest pain. In people who have healthy hearts, palpitations may cause a
pounding or thumping sensation that can be painful or uncomfortable, rather
than the heavy, tight, or squeezing sensation, called angina, usually
associated with heart attacks. In people who have coronary artery disease, a rapid
heart rate can cause angina. How you describe your pain may help your doctor
figure out whether the chest pain is the result of an abnormal rhythm or angina.
In many cases, your doctor may not be sure based strictly on your description. So he or she will probably order an electrocardiogram (EKG, ECG) or further stress
testing to evaluate the rhythm or rule out angina.
