Does Lexapro (escitalopram) prolong qt only in high doses? I take very low dose betapace and wanted to try Lexapro (escitalopram) for anxiety/depression. Tried other ssris.

3rd try. Please have an EKG done on the combination to determine FOR YOU if your QT is prolonged. We're all different. One person won't have QT prolongation and another will on the same dose of medications. Really. Please believe me.
