Anastacia delays heart surgery
But the 40-year-old, who had a breast cancer op in 2003, is treating it with drugs for now.
‘The doctors say it's a weakness triggered by stress,’ she tells Hello!
‘I'll be sitting chatting and suddenly my heart will beat like I'm running a marathon. I've fainted backstage because I can't get rid of the palpitations.
‘They can fix it by putting two electrodes into my heart and shocking it, but I don't want more surgery right now, so I'm on medication. The side effect is fatigue.’
Anastacia’s new album Heavy Rotation is out now.
