What was thought to be a person drowning in the water at Lincoln Boulevard and Ocean Beach Park was a swimmer who had a heart attack.
The Long Beach Fire Department received the report at 5:33 p.m. on Sept. 4. They found a person in the water west of the Lincoln Jetty, officials said.
Fire department members went into the water: one on a surfboard and three swam to reach the person on what officials said was cardiac arrest.
On land, cardio-pulmonary resuscitation was administered and a defibrillator was used as the unidentified man was put on what is called a Reeves Stretcher and taken transported to the Boardwalk in the back of a rescue vehicle.
Responders then placed the man in an ambulance and advanced life support treatment was performed and he was taken to Mount Sinai South Nassau Emergency Department at Long Beach.
Officials said the man regained a pulse and was later moved to Mount Sinai South Nassau Hospital in Oceanside.
In addition to all the Long Beach Fire Department units, which under the direction of Chief John Marino and Assistant Chief Hadrick Ray, Atlantic Beach Rescue and the Lawrence-Cedarhurst Fire Department and Inwood fire departments responded to the scene. The Woodmere Fire Department provided mutual aid.
