Video-EEG Telemetry: 'telemetry' refers to two things being done at the same time.
In Video-EEG Telemetry, both an EEG brainwave recording and a video recording of your child are made.
Video-EEG Telemetry involves the recording of a child’s physical activity with a video camera along with simultaneous brainwave (EEG) recording via a computer. It is used mainly in the diagnosis of events that are suggestive of seizures. Video–EEG telemetry is used to distinguish epileptic seizures from non-epileptic events. It is also used to help the doctor diagnose the type of epilepsy syndrome your child may have.
During a Video-EEG telemetry admission, it is desirable for the patient to have their usual seizure events so these can be captured on the recordings. Staff will discuss options with the family to increase the likelihood of recording these events. This may include having your child engage in tasks likely to bring on their typical seizures, or having their medication doses temporarily altered. Your doctor will give you very specific instructions around this.
If your child has an event while having telemetry, the doctors are able to review the video and corresponding brainwave recordings. If the recordings are indicating a seizure, characteristic patterns may appear in the brainwave recording.
If your child is booked in for a Telemetry study, it will most likely be done in a Children’s hospital. How long the study takes varies according to event frequency and other factors relating to the initial purpose of the study. The study may take several hours, overnight, or up to a week. Sydney Children’s Hospitals (Randwick and Westmead), only accept referrals from paediatric neurologists and paediatricians.
One parent or guardian is required to stay with the child at all times. If staying overnight, the parent/guardian will have access to a bed in the room with the child. The Video EEG recording needs to be reviewed by a neurologist. The results will be discussed with you during the follow up appointment.
