Melissa Yahle said she woke up Aug. 5 and realized something was wrong with her husband, Anthony, because his breathing didn't sound right.
She and son Lawrence, 17, performed CPR until an ambulance arrived and first responders could use a defibrillator, ABC News reported Thursday.
At Kettering Medical Center, cardiologist Raja Nazir said he discovered Anthony Yahle's arteries were clear and things looked good until the man coded. They worked on him for 45 minutes, giving him every medicine they could, but he didn't respond and was declared dead.
When Lawrence found out his father was dead, he said he ran down the hall to see his father's body and yelled, "Dad, you're not going to die today."
Nazir said at some point after that, he noticed Anthony Yahle had a heartbeat again, about once or twice a minute.
"When I looked at the electrical activity, I was surprised," Nazir said. "I thought we'd better make another effort to revive him."
Nazir said Anthony Yahle was back at home, resting comfortably by Aug. 10, with no need for a heart transplant. The cause of his medical emergency was not reported.
"I'm calling it a miracle because I've never seen anything like it," Nazir said.
