How It Feels
If you have electrodes placed on your skin, the electrode sites may itch slightly during the ambulatory EKG
recording, and the skin on your chest may look or feel irritated when the
electrodes are removed. The recording unit is very lightweight, so carrying it
usually is not uncomfortable.
There is no risk from ambulatory EKG monitoring. The electrodes
placed on your skin detect only the electrical signals from your heart. No
electricity is sent through your body, and there is no possibility of receiving
an electric shock.
An ambulatory electrocardiogram (EKG or ECG) is a test that records
the electrical signals that control your heartbeat while you do your everyday
Results of ambulatory EKG monitoring usually are interpreted by a
cardiologist or cardiac electrophysiologist. The results are generally available in a
Ambulatory electrocardiogram (EKG or ECG)
No abnormal heart rhythms are found in the EKG information
collected by the recorder. Your heart rate may go up when you are active and go
down when you are sleeping.
Many kinds of irregular heartbeats can be detected by
- Abnormal slow or fast heart rhythms are
detected. Alternating slow and fast rhythms may also occur
- A slow heart rhythm in a person with a
pacemaker may mean that the pacemaker is not working
- Abnormal patterns may mean that the heart muscle is not
getting enough oxygen (ischemia) because the arteries feeding the heart are too
The results of ambulatory heart monitoring are compared with your
medical history, symptoms, and other test results. You may need to have the
test repeated if the results aren't clear.
What Affects the Test
You may not be able to have the test or the results may not be
- You do not keep a detailed diary of your daily
activities and symptoms. The intermittent recorder will give accurate results
only if you remember to start the recorder when symptoms of possible heart
- The electrodes are not in the right spot.
