Iowa State coach Fred Hoiberg underwent surgery to replace his heart pacemaker and was expected to be discharged from the hospital on Tuesday afternoon.

The 41-year-old Hoiberg traveled from Ames, Iowa, to the Mayo Clinic in Rochester, Minnesota, for the procedure.

"The surgery performed this morning at the Mayo Clinic to replace my pacemaker was successful," Hoiberg said. "The plan is for me to be discharged and allowed to return to Ames this afternoon.

"I want to thank my doctors and nurses at the Mayo Clinic, as well as everyone that has extended their well-wishes to me. Our family truly appreciates your support."

Hoiberg's wife, Carol, tweeted afterward, "Surgery went well and @ISUMayor32 is RECHARGED"

The pacemaker originally was implanted during open-heart surgery in 2005 for enlargement of the aortic root. Hoiberg learned last weekend while working out at home that the pacemaker's batteries needed to be replaced.

"I'm so hypersensitive that I can feel every heartbeat," Hoiberg said, according to The Des Moines Register. "My (heart rate) isn't supposed to go below 70, but I could feel it was lower. I could just feel it. I'd do a workout, and when I got done, I could tell my heart rate wasn't elevating. It wasn't going past 65."

Hoiberg, a former Iowa State and NBA player, became the school's head coach in 2010 and has guided the Cyclones to three consecutive NCAA Tournament berths.
