A British teen, 16, is at Celebration Hospital in Kissimmee after falling ill at the Tower of Terror ride at Disney-MGM Studios, said Orange County Sheriff's office spokesman Jim Solomons.

The teen, whose identity has yet to be released, was exiting the ride with her mother at 9:50 a.m. today when she complained she was feeling unwell. Disney employees approached the girl and called paramedics because she needed medical attention, Solomons said. Paramedics arrived at 9:57 a.m. to transport her to the hospital.

The teen lost consciousness and heart function, but medical personnel revived her, Solomons said. She is being evaluated for a prior medical condition, and the ride is being tested for malfunctions.

The incident comes less than a month after a 4-year-old boy from Pennsylvania collasped on Epcot's Mission: Space ride and later died. The boy, Daudi Bamuwamye, was visiting the park on June 13, and authorities are awaiting results of an autopsy before saying what caused his death.
