A 910-pound woman had to be rescued through the window of her second-floor Harlem apartment Friday afternoon after suffering from an undisclosed medical condition, authorities said.

The woman, 70, was hoisted in a large yellow net by FDNY paramedics from her Fifth Avenue home and rushed to St. Luke’s Hospital, where she was listed in stable condition.

“Firemen came down and measured the elevator door,” the building doorman said. “She would not have been able to get out of the door.”

Firefighters tried to take her through her apartment door before opting for the window.
