title: Ask the doctor. I have had dizzy spells every few weeks for years. My doctor has done a lot of tests, including a Holter monitor, but nothing has turned up. I am most concerned about whether I could be having heart-rhythm problems, but my Holter was apparently normal. Should I be undergoing other tests?
