A U.K. man collapsed and died from a heart attack at his office Christmas party - after dancing to Gangnam Style.

Eamonn Kilbride, 46, had been doing the energetic horse-riding style moves to Korean pop sensation Psy's hit song with his co-workers - but seconds later suddenly dropped to the floor.

The tragedy occurred at an office party for the Thwaites brewery, in Blackburn, Lancashire, where Kilbride worked as an IT manager.

His wife Julie was with him, celebrating her birthday, at the Whitehall Country Club in Darwen, Lancashire, when he began to complain of chest pains. She desperately tried to revive him with CPR.

Paramedics who were on the scene five minutes later also tried to revive him, but he was pronounced dead as he arrived at Royal Blackburn Hospital shortly after 11:30 p.m. on Saturday.

The family, who live in Burnley, said the coroner told them that he had suffered from acute heart failure.

Julie paid tribute to a "loving husband" who she had been married to for 23 years. “I want people to know how he would help anybody whether it was a life-long friend, or someone he had just met," she said.

“We were having a fantastic time at the Christmas party and Eamonn had just finished dancing to Gangnam Style," Julie said of the incident. "He was up on stage and entertaining everybody.

“He said he had a bit of a pain and just collapsed."

Julie continued: “Eamonn was such an intelligent man, he inspired our children and made sure they had a good education. He loved me dearly and would tell people all the time. I know he thought the world of us.”

An initial investigation was launched into Kilbride’s death by police, but officers quickly established no suspicious circumstances.
