A 24-hour holtermonitoring is a test that records your heart rhythm for 24 hours.

The purpose of 24-hour holtermonitoring is to assess :

• Your heart rate for 24 hours
• Correlate your complaints or symptoms with possible heart rhythm abnormalities.
• To diagnose an abnormal heart rhythm: what type of arrhythmia, the frequency of occurrence of this arrhythmia, the duration over time of these arrhythmias and possibly the cause of these arrhythmias.
• Determine the treatment of choice for cardiac arrhythmia.
• Evaluate the effectiveness of the treatment.

Conduct of the examination :

Self-adhesive electrodes will be placed on the skin of your chest and connected to a small portable ECG machine. While wearing this device, it is desirable that you carry out normal daily activity, as close to your usual activity as possible. You are asked to make a note of the symptoms you experience and the time they occur.

Intracardiac monitor, pacemaker and defibrillator control

If you have a pacemaker, a subcutaneous holter or a defibrillator, please mention this when making your appointment. These devices are checked in the same way as an ECG recording. The examination takes between 5 and 10 minutes.
