Scuba diving with hypertension?

I want to learn how to dive, it's on my list of "things to learn someday" and I've decided that, since I'm not getting any younger, I should get started. I'm mildy hypertensive, I take medicine every day to keep my blood pressure down, and from what I've been reading (the PADI medical form, DAN information) having CONTROLLED high blood pressure should not be a problem for diving. Is this correct? Thanks for your help!
