24-hour ECG (holter ECG)
A holter recording is a test that examines how your heart functions over a long period of time.
A small box is used to record your heart rhythm for 24, 48 or 72 hours.
The study
Four electrodes are stuck to your chest using stickers. These are connected by a cable to a small box. You will carry this box with you throughout the examination. It continuously records your heart rhythm. As the box must not come into contact with water, you should not swim, shower or bathe during the examination. Apart from these activities, you should do everything you would normally do.
In the unlikely event of a sticker or cord coming loose, this should be repaired as soon as possible.
After connecting the box, you will be given a Holter diary in which you can record all details. You should record both activities and complaints in the diary. The cardiologist will compare the details you record with the ECG in order to correctly interpret the examination. You will be given an appointment to disconnect the box.
Duration of the study
24 - 72 hours
Results of the study
Results are generally known within 48 hours. You will have an appointment with the cardiologist to discuss the results of the test.
