Dr Tobin said: "It was 48 minutes when he collapsed to reaching hospital and a further 30 minutes after that. He was, in effect, dead at that time."
He added: "We were fearing the worse and didn't think we would get the recovery we had. It's incredible."
The Consultant Cardiologist who ran onto the pitch, Dr Andrew Deaner said: "If I was ever going to use term miraculous it could be used here. He has made a remarkable recovery so far. "Two hours after [regaining consciousness] I whispered in his ear, 'What's your name?' and he said, 'Fabrice Muamba'. I said, 'I hear you're a really good footballer' and he said, 'I try'. I had a tear in my eye."
