Tracey Hermanstorfer's heart stopped beating and her son Coltyn appeared lifeless after the Caesarean(剖腹产术)section on Christmas Eve. However a few minutes after he was born, both began breathing again. Dr Stephanie Martin told Good Morning America she could not explain how the pair survived. Mrs Hermanstorfer and her husband Mike told the American television show that their baby was now healthy and that they were doing “good” following the drama at Colorado Springs Memorial Hospital.

The couple, who already had two children, had to go into the hospital seven weeks earlier than planned. Her husband, 37, said his wife was tired after receiving an epidural(硬脑膜外麻醉)during the labour(分娩)but after closing her eyes, she “wasn't waking up”．She stopped breathing and she is believed to have suffered a heart attack before her heart stopped beating entirely.

Dr Martin said she was called in and that the outlook was grim（严酷的） since in most situations like this，“despite the best efforts of the team”, the mother was often unable to be revived. In that case doctors then tried to focus on delivering the baby but when he was born he was “completely lifeless”．

Mr. Hermanstorfer told the Associated Press news agency，“I had everything in the world taken from me, and in an hour and a half I had everything given to me.”

Dr Martin said she did not have a“great explanation”for why Mrs Hermanstorfer's heartbeat returned. “Somewhere between four and five minutes she had been without heart rate and had stopped breathing a minute or two prior to her heart stopping，”she said. The doctors were then able to bring the baby back to life, and the mother was alive after that.

Despite tests, she said doctors were still not sure about what had happened. However Mrs Hermanstorfer and her husband Mike have said they believed it was down to a miracle. She said：“I got a second chance in life.”
