What is a Holter monitor?
A Holter monitor is a portable device that measures and records your heart’s activity continuously for 24 hours. The device is the size of a small camera. It has wires with silver dollar-sized electrodes that attach to your skin. The Holter monitor records your heart’s activity as you go about your daily activities.
Why do people wear Holter monitors?
Regular electrocardiograms (ECGs or EKGs) let your doctor look at your heart’s activity at one point in time during your ECG test. But abnormal heart rhythms and cardiac symptoms may come and go. That’s why your doctor may want to evaluate your heartbeat over time while you go about your normal activities. You may be asked to wear a Holter monitor if you have fast, slow or irregular heartbeats called arrhythmias.
Wearing the monitor may tell your doctor:
- If your medicines are working.
- Why you have symptoms such as dizziness, faintness or the feeling that your heart is racing or skipping a beat.
- If your heart is getting enough oxygen to meet its needs.
What are the risks of Holter monitors?
Wearing a Holter monitor has no risks and causes no pain. Holter monitors have wires that connect to small discs (electrodes) attached to your chest to record the electrocardiogram. Because the electrodes are attached with tape or adhesives, they may cause mild skin irritation. Tell the technician if you are allergic to any tapes or adhesives.
