What is Ambulatory Cardiac Monitoring
Ambulatory Cardiac Monitoring is used to detect abnormal heart rhythms (arrhythmias). Most monitors are connected by wires to flat, sticky disks (electrodes) that are then attached to your chest. You may need to wear a monitor if you have had symptoms such as:
- Fast heartbeats (palpitations).
- Dizziness.
- Fainting or light-headedness.
- Unexplained weakness.
- Shortness of breath.
There are several types of monitors. Some common monitors include:
- Holter monitor. This records your heart rhythm continuously, usually for 24–48 hours.
- Event (episodic) monitor. This monitor has a symptoms button, and when pushed, it will begin recording. You need to activate this monitor to record when you have a heart-related symptom.
- Automatic detection monitor. This monitor will begin recording when it detects an abnormal heartbeat.
What are the risks?
Generally, these devices are safe to use. However, it is possible that the skin under the electrodes will become irritated.
How to prepare for monitoring
Your health care provider will prepare your chest for the electrode placement and show you how to use the monitor.
