What is a Holter monitor?
The Holter monitor is a 24-hour continuous recording of the child's electrocardiogram (eh-lehk-troh-KAR-dee-oh-gram) or ECG. It permits recognition of any rhythm problem of the heart which may occur during daily activities. Cardiogram leads are placed on the child's chest and attached to a small tape recorder which can be hooked to a belt or carried on a strap. While wearing the Holter monitor, a diary of the child's activities should be kept, and especially report any complaints which may be related to the heart. If cardiogram leads become loosened or detached from the chest with activity, they can be reinforced with tape. A shirt or blouse which buttons in front is suggested when the Holter is put on the child.
What happens when the monitor is removed?
After the monitor has been worn for 24 hours, it is taken off and brought or sent to the clinic to be read. If you live a long distance from C.S. Mott Hospital, the unit can be mailed to us in a special postage paid, self-addressed cardboard package which will be provided for you. The taped ECG is scanned electronically to see if there are any abnormal heartbeats. If any significant problem is found, the family is notified immediately.
