Kathy Margiasso, the fitness director at Mount Kisco Athletic Club, and another personal trainer were waiting for their 9 a.m. appointments last week when a member came running toward them.

“Someone fell off the treadmill,” Margiasso said was the urgent message.
Margiasso’s initial instinct was to grab the first aid kit, thinking it might be a case of scrapes and bruises, but then fellow trainer Val Yasovic told her the person was unconscious.

Turns out a 64-year-old man had suffered a heart attack while working out on the treadmill. Margiasso said she quickly “turned back around,” and got the Automatic External Defibrillator, or AED, and told manager Tom Brady to call 911.
“Immediately what I did was just open the AED and put the pads on his chest, and the AED analyzed immediately and said there was a shock advised,” Margiasso said. “I did one shock and then we started CPR.”
Brady said Margiasso and Yasovic were in sync.
“She and Val worked as a team to save that guy’s life,” said Brady, noting that one trainer was operating the defibrillator and then together they did three cycles of CPR with Margiasso doing compressions and Yasovic the breaths.
Margiasso said the victim’s legs then started to move “and there were signs of life” so she stopped. By this point, police, EMTs and an ambulance had arrived at the 151 Kisco Ave. club
The club would not release the name of the member who was stricken but said he was stabilized at Northern Westchester Hospital in Mount Kisco and then brought to the cardiac unit at Westchester Medical Center in Valhalla where he underwent double bypass surgery the following day.
Margiasso said Tuesday she was proud of herself and the staff for remaining calm and grateful that everyone in the gym is trained to do CPR and use the AED. In fact, Margiasso is the one who trains them.
“I’m thrilled that when it comes time to put (to use) the skills that we practice over and over again, that we were able to do it,” she said.
