Cardiology - 24-hour Ambulatory ECG Monitoring

An electrocardiogram (ECG) is a recording of the heart’s electrical activity. A 24-hour ambulatory ECG monitoring test, also called the Holter monitoring test, records heartbeats over an entire day so that as many as 100,000 heartbeats are recorded by a recorder worn by the patient. In contrast, routine ECGs record your heartbeats over a period of 10 seconds. These ECG records are then analysed to look for any abnormalities in heart rhythm and rate.
