Howie Mandel is expected to return to the Howie Do It set on Wednesday after he collapsed during a shoot and was sent to a Toronto hospital.

Mandel, 53, was shooting a new episode of the hidden-camera prank show in which he and a team of disguised pranksters perform hoaxes and tricks on unsuspecting targets.

But the unscripted TV series took a bizarre turn at the Sheraton Centre Hotel in Toronto at 7 p.m. on Monday night when Mandel suddenly fainted in front of crew and family. Paramedics were called to the hotel, where they found Mandel conscious and breathing, but experiencing chest pains.

Mandel was transported by ambulance to St. Michael’s Hospital, where doctors kept him overnight for observation. Production on the Global series was halted.

The Canadian comic-turned-TV host’s publicist Lewis Kay in an e-mail statement denied Mandel had suffered a heart attack during the on-set medical scare.

Kay said Mandel was monitored for an ‘irregular heartbeat’ by doctors, who released him on Tuesday morning.

Without disclosing any additional medical information, Kay added Mandel was expected to return Wednesday to location shooting on Howie Do It in and around Toronto.

‘He appreciates everyone’s concern,’ Kay said.

Howie Do It, a coproduction between Global Television and NBC and produced by Mandel’s production shingle, bowed last Friday with lucky sevens: 770,000 total viewers on Global Television, and 7.7 million viewers stateside.
