First two paragraphs form focal Chicago report about Chicago Marathon: The successful defibrillation was treated almost with a yawn. That's super because it means that (a) there was a defibrillator on scene and there is a growing expectation that it will be there and used.

"One man suffered cardiac arrest in the last miles of the race, but cool weather kept injuries down in this year’s Bank of American Chicago Marathon, race officials said. The cool weather provided nearly ideal conditions for runners, and the men’s winner broke the course record.
"At mile 21, a 47-year-old runner suffered cardiac arrest but was shocked twice by medical personnel, regained consciousness and was taken to Mercy Hospital, where he was alert and talking to staff, officials said. They would not identify the runner or his hometown. Nine other participants were transported to hospitals, which is 50 to 60 percent fewer than in recent years."
