Holter Monitoring

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.
