SPRING TWP., Pa. - February 15, 2011 (WPVI) -- Though Mary Beth Esposito doesn't remember the day, her husband, Steven, does.

It was the day his 45-year-old wife suffered a heart attack. Her physicians now say that for two minutes she was dead.

"I looked at her chest, she wasn't breathing, and I called 911 right away," Steven said.

By chance, Spring Township Police Officer Nathan Getz and Sgt. Todd Peterson were patrolling just blocks away and heard the EMS dispatch on police radio.

They were at the Esposito's home within moments.

But more importantly, their squad cars were equipped with defibrillators.
