Holter Monitoring

What is a Holter monitor?

The Holter monitor records the electrical activity of your heart during normal daily activities and through the night.

How is a Holter monitor performed?

A technician or practice assistant will stick on 5 small electrodes to chest wall. These electrodes are connected to a small portable recorder (roughly the size of a mobile phone). You will be asked to wear this monitor for 24 hours before returning it.

You should press the Event Button on the recorder if you feel any symptoms such as chest pain, abnormal heartbeats or dizziness while wearing the monitor.

Why is a Holter monitor performed?

A Holter monitor gives us the opportunity to record the electrical activity of your heart over a 24 hour period. It is useful in diagnosing heart rhythm disorders that you may not have known about. It can be used to detect abnormalities of the heart that cause intermittent symptoms. It is also used to monitor response to treatments such as heart medications, pacemaker insertion or ablation procedures.

Do I need to prepare for a Holter monitor?

Yes. You cannot take a bath or shower with the monitor on because it is not waterproof. It can be concealed easily with normal clothes should you wish. You should perform all your usual daily activities
