How is the test done?
You will be taught on how to use the ECG recorder on the day of your appointment.  

The device will be loaned to you for 2 weeks. Different models of device are available and the medical technologist (MT) will get you a device that is most appropriate for your needs. You will be provided with a small portable device with or without wires for attachment to your chest. When the device is handed to you, you are required to sign a loan agreement upon which you agree to bear the cost of the device if it is lost or damaged. It is advisable that you handle the device with care.

If there are no recordings / transmission during the initial 2 weeks, the loan may be extended for another 2 weeks. This extension is subject to the availability of the device and you will be charged for its extended use. 
When you experience symptoms (e.g. palpitations, giddiness or chest pain), activate the device immediately. If you are not wearing the device when the symptoms occur, you must quickly set up the connection and activate the device immediately.

During recording, please remember to record the date and time of the symptoms. When it is convenient, please transmit your ECG as soon as possible to the NHCS receiving centre with the telephone number (Tel: 6844 9178) as instructed by the MT.

The recording will be processed and analysed. A doctor will then interpret and discuss the results with you at your next follow-up consultation.
