Holter monitoring is a continuous recording of the EKG for 24 to 48 hours. The patient may continue daily activities during the time the holter is being worn. This test may detect abnormal heart rhythms or arrhythmias. The EKG is recorded on a small recorder. Seven electrodes will be placed on the patient's chest. These electrodes are attached to wires that are connected to the recorder.
A diary is kept of activities during the time the recorder is worn. It is important to record all symptoms and activities. At the end of the 24 to 48 hours the recorder will be removed, the tape scanned and a reading will be obtained from a physician. Loose fitting blouses or shirts with the buttons in the front should be worn the day of the monitor application. Do not take a bath or shower, swim or do anything that may get the electrodes, wires or recorder wet. Avoid electric blankets, magnets, metal detectors, and high-voltage areas that may cause interference on the tracings. Thirty minutes should be allowed for the preparation for this test. A physician will read the test.
