She was always running around and getting into everything. Then one day she got very sick. Something went wrong with her heart. It began to beat too fast, then too slow.

　　Florence and Sam took Shy-Anne to the animal doctor. The doctor had a surprising answer to Shy-Anne's problem. He put a tiny machine in her heart. The machine was called a pacemaker(心脏起搏器). It kept her heart beating evenly.
