What is a Holter Monitor? 

A Holter monitor is a type of portable electrocardiogram (ECG). The device is used to continuously record the heart's activity during normal day to day activities, most often over a period of 24 hours. 

How can I prepare for a holter monitor? 

There are no special preparations for this test. However, patients will need to wear the device for 24 hours and will be unable to shower or swim during this period to ensure that the device does not get wet. 

Some of the chest may require shaving to attach the electrodes to ensure secure attachment. It is advisable for women to wear a bra even while sleeping to ensure that the device stays securely in place. 

Patients will need to allow 10 to 15 minutes for the device to be fitted and may remove the device the following day at the same time when returning it back to the clinic.
