Former Vice President Dick Cheney wasn't among those critical of the show "Homeland" for last season's story line — which included terrorists using the Internet to remotely deliver a fatal shock to the fictional vice president's pacemaker.

Cheney told "60 Minutes" in an interview set to air Sunday that his cardiologist disabled the wireless function of the defibrillator he had implanted in 2010 for that very reason.

"I was aware of the danger... that existed... I found it credible," Cheney said.

"I know from the experience we had and the necessity for adjusting my own device, that it was an accurate portrayal of what was possible."

Cheney has suffered five heart attacks in his life, resulting in multiple angioplasties and catheterizations. He also underwent a quadruple bypass operation.

But the former vice president told CBS his heath problems did not impact his work.

"Getting back to work...was important enough that I, in fact, kept them separate...I always did what I needed to do in order to deal with the health crisis in the moment," Cheney said.
