What is an AFT 1000 ?

The AFT 1000 is an electrocardiogram (ECG) recorder used for long-term recordings. The electrodes for this device are generally placed for 15 days, however they may also be placed for several weeks.

This examination is used to detect heart rhythm disorders that are not actually felt or which occur only rarely. This device can also be used to monitor the effectiveness of a medical treatment.

This examination is painless and does not interfere with your daily activities. You will continue to take any medications prescribed by your doctor. 


There is no need to fast prior to the placement of the electrodes and there is no risk associated with this device.

Electrode placement

At the scheduled time, please go to the secretary's office in the cardiology unit on the first floor of the annex. A nurse will set up the device. This will not take long (approximately 15 min.).

Three electrodes will be attached to your chest (see the photo). A device, the size of an MP3 player, will be connected to the electrodes. 

You will also be given a logbook to record your observations.

If you have any symptoms, press 1x on the green button

To ensure a good quality of the recording

  • Keep your mobile phones/tablets/MP3 players/computers away from the recorder
  • Do not wear any jewellery around your neck
  • Do not wear wool or synthetic underwear and instead wear cotton clothing
  • Women should not wear bras with underwires
  • Remember to make sure that the device is still working from time to time, press the grey button and a small wheel will appear


CAUTION: The device is not waterproof; do not take a shower while wearing the device. 

You may take your shower while wearing the electrodes (they only need to be replaced every 2 to 3 days).

After your shower, be sure to dry the electrodes with a towel and possibly with a hair dryer. Replace any electrodes that may have possibly become disconnected.


  • Regularly check that the electrode is properly attached to your skin. If an electrode becomes detached, re-attach it as quickly as possible. You will be given replacement electrodes
  • Avoid scratching yourself as much as possible

For recordings longer than 24 hours:

  • We advise that you change the electrodes every 2 or 3 days. Reposition them as per the following diagram: 

  • If the electrodes cause a skin reaction, change them more often and don’t hesitate to move them a few cm to a non-irritated area. 

Returning the device

The nurse will tell you the date and time you will need to bring the device back. Please go see the secretary when you arrive. 

The waiting time is very short (approximately 15 min.), unless you have to wait for the results and see the cardiologist. In this case, you should expect to have to wait approximately 45 minutes for the recordings to be read and then between 45 min. and 1 hour and 15 min. to see the cardiologist. Please make all necessary arrangements. 

When you arrive in our ward, please let us know if you have any scheduling problems (for example: children that need to be picked up from school, appointments, etc.).

Thank you for your cooperation.
