Electrocardiograms (ECG)
Holter monitoring for children
ECG Holter monitoring for a child is a safe and painless test that continuously records a child's heart rhythm over an extended period of time under everyday conditions. It helps the doctor detect temporary or irregular heart rhythms and assess the child's heart function.
What is it?
Holter monitoring is a safe and painless heart test that allows the doctor to monitor the child's heart rhythm for an extended period of time – not just a few seconds, as during a regular ECG, but around the clock or even for several days.
During the examination, a special device records the electrical activity of the heart. This helps to detect temporary or irregular changes in the heart rhythm, which are often missed during a regular ECG recording. Holter monitoring allows the doctor to see how the child's heart is working both at rest and during everyday activities – studying, playing, running or sleeping.
This method is completely safe because no radiation is used and the device has no effect on the body – it only records the heart's electrical signals.
Children usually get used to the device within the first hour and can continue with all their usual activities. For younger children, the doctor or staff will explain the examination in a simple, understandable way, and parents may be present during the procedure.
How is it done?
At the beginning of the examination, a doctor or nurse sticks several small electrodes to the skin of the child’s chest. These are connected to a small recording device called a Holter monitor, which the child wears throughout the examination. The monitor is usually attached to a belt or placed in a lightweight case that is worn over the shoulder or around the neck. The device is light and comfortable, and the child can move around freely, play, and go to school.
The electrodes "listen" to the heart's electrical impulses, but do not conduct current through the body, so the child does not feel anything – neither pain nor tingling.
The examination takes place during the child's usual daily routine so that the heart rhythm is observed most naturally.
Holter monitors can be of two types:
-
classic monitors with multiple electrodes and wires that provide very accurate information about heart activity;
-
Wireless monitors that attach directly to the chest are smaller and more comfortable, but have lower recording quality and are more likely to be designed for shorter recordings (e.g. 24 hours).
The doctor chooses the most appropriate monitor depending on the child's age, complaints, and duration of the examination.
Once the specified period (usually 24–48 hours, sometimes up to 7 days) has passed, the child returns to the clinic, where the monitor is removed, and the data obtained is analyzed by a doctor to assess the heart rhythm in various situations.
When is an examination necessary?
Holter monitoring is usually recommended for children if a regular ECG fails to record the heart rhythm at the time of the complaint, but there is suspicion of heart rhythm disturbances or temporary changes. Your doctor may recommend this test if:
-
the child has heart palpitations or a “thumping” sensation;
-
chest pain appears, especially during physical exertion;
-
the child has had dizziness, fainting or a temporary loss of consciousness;
-
fatigue, weakness, or shortness of breath for no apparent reason;
-
irregular or uneven heartbeat;
-
it is necessary to assess the effectiveness of treatment in case of heart rhythm disorders;
-
the pacemaker should be checked;
-
the doctor wants to monitor the heart rhythm long-term, for example after an infection or surgery;
-
in other situations, upon the doctor's advice.
Holter monitoring helps not only to make a diagnosis, but also to understand how a child's heart reacts to various stresses, emotions, or rest.
How to prepare for the examination?
Holter monitoring for children does not require any special preparation, but some practical suggestions will help make everything go smoothly and ensure the data is accurate:
-
It is advisable for the child to take a bath before applying the device, as showering is not allowed during the examination – the device is not waterproof.
-
Do not apply creams, oils, or lotions to the child's chest on the day of the examination – they may interfere with the adhesion of the electrodes.
-
Choose loose, comfortable clothing for your child so that the electrodes and device are hidden and do not hinder movement.
-
Continue to give your child their usual medications unless the doctor has given you other instructions.
-
Let your child live a normal daily routine – the child can play, go to school, or go outside, because this is what helps to achieve the most realistic results.
-
Keep a diary of when the child does exercise, rest, or experiences any symptoms (such as palpitations or dizziness). This will help the doctor later compare the symptoms with the data recorded on the monitor.
