What is Holter Monitoring (24 or 48 hour)?
Holter monitoring is a continuous recording of the electrical rhythm of the heart and is usually carried out over 24 or 48 hours. In some cases the monitoring period can be extended to one or two weeks. It is generally used to investigate symptoms of palpitations (rapid or uncontrolled heart beat) which may not be picked up by an ECG
How is it done?
The device consists of a small recording device (a little larger than a phone) attached to three electrodes which are connected to the chest and abdomen. An area of the chest may need to be shaved to facilitate lead placement. The recording device can then be worn around the waist or on a strap across the chest. This should not interfere with normal daily activities
You will also be asked to keep a diary of symptoms’, so that these can be correlated with any change in heart rhythm.
Holter monitoring is a very safe procedure with no major risk involved. Occasionally, patients can develop a skin reaction to the small electrode pads which are used which will resolve once the device is removed.
