What is a Holter / Loop Heart Monitor?
A Holter / Loop Monitor is a small wearable device that records the electrical activity of your heart, over a set period of time, to detect any abnormal heart rhythms.
Why is it done?
Your doctor might request a holter / loop monitor to:
- Check for signs of irregular heart rhythms (arrhythmias)
- Evaluate your heart rhythm over a set period of time
- Determine the cause of unexplained fainting
- Evaluate a heart condition that increases the risk of arrhythmias
How do I prepare?
You can eat normally and take your medications, at their usual times, before the test. We recommend patients:
Wear a loose, comfortable two-piece outfit.
Bathe or shower in the days (or hours) before your test. You may not be able to bathe, shower or swim during your testing period (dependant on the type of monitor you receive).
What happens during the holter / loop monitor test?
A technician will explain the process and attach the holter / loop monitor:
- Your technician will place electrodes (sensor stickers) on your chest. These electrodes detect your heartbeat.
- If you have hair on your chest, areas may be shaved to ensure the electrodes stick.
- Wires attached to the electrodes connect to the Holter / Loop monitor recording device.
- Once your monitor is fitted, you can leave the clinic and return to your everyday activities.
After the prescribed time period, you can remove the monitor and cuff and return it to the clinic or as instructed by the technician.
