When Zoe woke up in the morning her heart was beating very slowly. After biking to school her heartbeat was very fast. While sitting at her desk her heartbeat was normal. At playtime, Zoe played tag and her heartbeat was very fast. During reading time, she felt sleepy and her heartbeat had become very slow. At lunchtime Zoe went to kapa haka practise and her heartbeat went really fast. She then went inside to listen to a story and her heartbeat went back to normal.
