A Holter monitor is a small device that is worn for 24 hours and is generally used for patients who may experience symptoms of abnormal heart rhythms (arrhythmia) one or more times a day. The test is painless and you will be able to continue normal activities during the 24 hour testing period. If you experience any problems with the Holter monitor, contact our office immediately. Results are available to the referring physician within 24 hours.
No preparation is needed before your provider starts the monitor. Ask your provider if you have any questions about this test.
During a Holter monitor test, electrodes are attached to your chest and wired to a small monitor that will record your heart’s electrical activity over the next 24 hours. The monitor can be worn on your belt or over your shoulder on an accompanying strap. The monitor records every heartbeat over the test period, which is then analyzed for the presence of heart rhythm irregularities. Upon completion of the test, the monitor is returned and analyzed by Everett Clinic technicians.
