Miley Cyrus suffering from heart disease

LONDON - ‘Hannah Montana’ star Miley Cyrus is suffering from a heart condition.

The pop star-actress has revealed in her autobiography ‘Miles to Go’ that she has tachycardia, meaning her heart rate exceeds the range of a normal resting heart rate, reports contactmusic.com.

Although the condition is not life-threatening, Cyrus admits she struggles to deal with it.

‘The type of tachycardia I have isn’t dangerous. It won’t hurt me, but it does bother me. There is never a time onstage when I’m not thinking about my heart,’ the autobiography reads.
