NYPD heart-start effort

The Big Apple is getting a big jolt.

The NYPD will now make sure that there are at least several defibrillators in every one of its station houses, transit bureaus, and the housing projects it polices, officials said.

The devices, which are also employed by the Fire Department and EMS, are used to jump-start the hearts of patients in cardiac arrest.

New York’s Finest have saved 54 people since they started using defibrillators in 1997, authorities said.

Michael Kiernan, 51, is one lucky survivor.

When he collapsed after suffering cardiac arrest on a downtown D train last year, a transit cop ran in with the lifesaving device at the 59th Street station and Kiernan opened his eyes after two shocks.

“It really is like winning the lottery,” said Kiernan. “I got a second chance at life.”

Only 1 to 2 percent of people who suffer cardiac arrest actually survive, according to the American Heart Association.

“It is very encouraging that they are expanding the program,” Kiernan said. “[Defibrillators are] the reason you are alive, in combination with the people who use them.”
