Back at home in Ashton-in-Makerfield, Isobel said she had taught both Joshua, now three, and his older sister Amy, six, how to dial 999 in an emergency as soon as they could talk because her heart condition makes her prone to passing out.
She said: "Amy has done it before, but she was at school this time. I didn't know anything about it until I woke up with a paramedic standing over me.
"Joshua did really well. I'm really proud of him."
