A continuous ECG that is done over 24-48 hours while you perform your normal daily activities.
A Holter Monitor is a continuous electrocardiogram (ECG) taken while you are performing your normal daily activities over 24 or 48 hours. Monitoring electrodes will be put on your chest by a technician during your initial appointment. These electrodes will pick up the signals from your heart and transfer them to the portable recorder. The recording will later be transformed into a report, which your doctor will analyze.
There is no specific preparation for this test, beyond wearing a loose fitting shirt or blouse (no dresses, please). Just remember that once the Holter Monitor is applied, you will be wearing it for 24 or 48 hours. The recorder you will be wearing should not interfere with your normal routine, and there are only a few restrictions while wearing it, please take note of these restrictions below.
