When your child needs to have an ECG to check their heart signals it can be helpful to prepare them through pretend play. This video by the What? Why? Children in Hospital charity shows how you could play with your child the day or morning before you go to hospital. By using strings, stickers and a cereal box as the recording computer they prepare Lewis the lion for his ECG. This video with pretend hospital play is aimed at younger children and those at an early stage of development.
