19 Dec Holter ECG
Alternative Names: 24-hour ECG, Ambulatory ECG
A holter ECG (electrocardiogram), or 24-hour ECG, monitors the electrical activity of the heart when the doctor needs more information about irregular heartbeat (arrhythmia), heart palpitations, fainting, chest pain, and suspected angina. The test is carried out while you go about your normal activities. Small electrodes, attached to a recording device (holter), are placed on your chest. You carry the device around with you for the period of the test.
What is it?
A holter ECG (electrocardiogram) is a test that monitors the electrical activity of the heart while the patient is going about his normal activities.
This test involves wearing a device (the holter) for a period of time, usually for 24 hours.
Why is it done?
This test is done when doctors need more information on a patient’s heart, often when an irregular heartbeat (arrhythmia) is suspected, but has not been observed/documented on a normal ECG. Common indications include:
- Episodes of palpitations or irregular heart beat
- Fainting episodes
- Chest pain/suspected angina
Before – how to prepare
No special preparation is necessary.
During – how the test is done
Small electrodes are attached to your chest. These electrodes are attached to a small recording device that may be worn around your neck or in a pocket/pouch. You wear this for the entire period of the test. Wearing the device may be uncomfortable but there is no pain and most patients cope well.
After the test
You return the device and your doctor will have the results available soon afterwards.
