Miley Cyrus Opens Up About Heart Condition

While promoting new book, Miley talks about her tachycardia as well as her heartbreak.

What “Hannah Montana” star [artist id="2408193"]Miley Cyrus[/artist] suffered when her relationship with [artist id="2088128"]Nick Jonas[/artist] ended is not the only heart ailment she’s talking about these days. In her new book, “Miles to Go,” the teen star is telling her fans all about another kind of heart condition she suffers from: tachycardia.

The non-life-threatening condition makes Miley’s heart rhythm exceed the range of a normal resting heart rate, reports “The Insider.”

“The type of tachycardia I have isn’t dangerous. It won’t hurt me, but it does bother me,” the 16-year-old wrote in her autobiography. “There is never a time onstage when I’m not thinking about my heart.”

Miley also thinks about her heart when she talks about her former flame, Nick Jonas , whom she called “Prince Charming” in the book. When she stopped by “The View” on Monday, he was once again the subject of conversation.

“It was great and it was fun, but I was really young,” she said of the relationship. “I live in a very mature world. … We’re just so busy. Unlike most 12-year-olds or 13-year-olds, we’re, like, ‘Oh yeah, I can’t hang out with you today ’cause I gotta go to work. … I’m in Germany doing a concert.’ And so that got hard.”

Although their love may have soured, she still holds a place for the young Jonas in her heart. “I still love him with everything in me,” she said. “I think he is the greatest. I get asked all the time who’s my favorite Jonas. Nick’s my favorite Jonas. I’m happy with our friendship.”

Another relationship that Miley addressed in the book is the one she shares with her father, country singer and “Hannah Montana” co-star Billy Ray Cyrus. “The media has said some stuff about my dad and me being too close and too cuddly for a father and a daughter,” she wrote, reports The Stamford Times. “For me and my dad, it’s not weird at all.”
