Holter monitoring is a test that records a patient's heart beat for 24, 48, or 72 hours plus 7 day and 14 day tests. It provides the doctor with a continuous reading of the patient's heart rhythm over specific time periods. There is no pain or risk associated with this test.
The holter monitor is a battery-powered device with highly sensitive electrodes—small disks that stick to a patient’s chest—that can pick up the heart's electrical impulses. It records what the heart is doing when a patient is experiencing chest pains or irregular heartbeats A doctor will use this recording to help to diagnose any problems and prescribe a treatment plan that best suits the patient's needs.
For this test, a patient has to visit the hospital to have the monitor fitted and to receive instructions on how to use it. A technician will place electrodes on the patient's chest. These electrodes are attached to wires called leads that connect to a small device to be worn on a belt around the waist. The patient is advised to carry on a normal routine and keep a log of all the daily activities. For patients who wear monitors for 24, 48, 72 hours you MUST NOT shower or bathe for the duration of the test, as it is important to keep the monitor and electrodes dry. Patients who are asked to wear monitors for 7 to 14 days will be supplied with additional replacement electrodes to permit bathing.
