Holter Monitoring and Event Recording
What is it for?
A Holter monitor is a portable device that keeps track of the electrical activity of your heart for 24 hours or more. An event monitor is worn for a longer period of time. When you feel symptoms, you will push a button and record your heart’s activity for just a few minutes. Both kinds of testing are used to determine how the heart responds to normal activity. They may be used after a heart attack or as a way to diagnose heart rhythm problems.
How is it done?
Long-term heart monitoring (ambulatory electrocardiography) is usually conducted away from the doctor’s office. Sticky electrodes are attached to your chest and connected to a small recording monitor. You carry the battery-powered monitor with you and can continue with your regular daily activities. Often you will be asked to keep a diary of what you do during the monitoring period.
