Just like an ECG records the electricity in the heart, the Holter monitor also records the electricity in the heart. However, the ECG only records the heart rhythm for 10 seconds. A Holter monitor on the other hand records the heart rhythm for 24 hours or even longer. It is important to document any symptoms in the provided diary during the recording period, so specialists can assess your child’s heart rhythm at the exact time of the symptoms.
Unlike an ECG, a Holter monitor only uses 5 leads. The recording device is small and can be tucked away under clothes. Normal activities can be undertaken, and you child can even go to school while wearing a Holter monitor. However, your child will not be able to swim, shower or bath while wearing the monitor.
