Jake LaMotta — the former middleweight boxing champ who inspired Martin Scorsese’s classic “Raging Bull” — has undergone pacemaker surgery at 92.

LaMotta’s wife, Denise Baker, told Page Six the pugilist had the procedure done last week at Mount Sinai Medical Center in Miami Beach.

“It was successful,” Baker happily reported to us, adding, “Hopefully he’ll live for another 10 to 12 years. God bless them and him!”

LaMotta just celebrated his 92nd birthday last month in the couple’s hometown of Bisbee, Ariz.

The May-December pair — Baker is the Bull’s seventh wife — starred together when LaMotta was a mere 90 in “The Lady and the Champ,” a show about his life in New York.
