24 Hour Electrocardiogram (EKG) Holter Monitoring

Holter monitoring is a method of recording your heartbeat or electrical activity for a full 24 hour period, in an effort to determine if your heart rhythm has any abnormalities. As with the standard EKG, electrodes are placed on the chest. The electrodes connect to a lightweight unit, which attaches to a belt or shoulder strap. While wearing the monitor you are instructed to keep a diary of activities that you perform and the time of day that the activities occur. This will assist your doctor in determining if any of the irregularities in your EKG are related to physical exertion, emotional stress, etc.
