What Affects the Test

You may not be able to have the test or the results may not be helpful if:

• 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 problems occur.
• The electrodes are not in the right spot.
