I Am Considering Cosmetic Surgery But Five Years Ago I

I am considering cosmetic surgery but Five years ago I was diagnosed with bradycardia or vasovagal syncope. I am a 54 year old , otherwise healthy, woman. My question: is it safe to undergo general anesthesia with this diagnosis? I recently had an EKG, which showed a "borderline" result. The cosmetic procedure is a facelift (quick lift) and brow lift.
