Ambulatory ECG monitor (24 hour tape)

What is it ?

An ambulatory ECG monitor is a small portable machine that records your heart rhythm continuously for between 1 and 7 days. This can provide a lot of useful information on your heart rate, in particular any tendency to fast or slow heart rhythms that may require treatment.

How is it performed ?

Three sticky pads (electrodes) are placed on your chest and connected by fine leads to a lightweight recorder. This is worn in a small pouch around the neck or on a belt for between 1 and 7 days. The physiologist will let you know when you need to return the recorder. You will also be given a diary card to record any symptoms such as dizziness or palpitation. These can be correlated with your heart rhythm when the recorder is analysed.

How long does it take ?

About 15 minutes to set up.

Are there any risks ?

None, although some chest hair may need removing. Do not get the machine wet or sleep with an electric blanket as this may damage the device. Please do not remove the electrodes or tamper with the machine. If one of the electrodes comes off, try and stick it back on with sticking plaster or contact the department for advice.

What happens next ?

Once you have returned you ambulatory ECG recording, it will be analysed and a report generated, usually within seven days.
