A 53-year-old man who went into cardiac arrest on a Metro-North train started breathing again after another passenger delivered CPR and officials shocked him with a defibrillator.



State troopers responded at about 12:50 p.m. Sunday to the Cortlandt Train Station on Memorial Drive in Montrose.



"Troopers arrived on scene and located a 53-year-old male in full cardiac arrest receiving cardiopulmonary resuscitation (CPR) by another Metro-North train passenger," authorities said. "Troopers immediately placed the automated external defibrillator (AED) on the subject and two shocks were administered."



Shortly thereafter the victim started breathing again on his own, according to officials. He was then transported to the Hudson Valley Hospital Center in Cortlandt Manor.



The heart stops during cardiac arrest. The American Red Cross considers the AED the "only effective treatment for restoring a regular heart rhythm during sudden cardiac arrest." The American Heart Association says the condition may be reversed if CPR is given and a defibrillator is used quickly.
