Sam shows us what happens when you get a heart monitor (Ambulatory ECG) in the children's hospital. The physiologist explains what to do when the stickers come off when you're at home, what you do with the heart monitor when you go to sleep, if you can take a shower and how long you need to wear it for.
WWCIH is a charity making videos to show what happens in hospital. More info on: www.wwcih.org.uk
