Abstract

This report presents a well-documented link between vasodepressor syncope, a marked increase of LF/HF ratio response to orthostasis (sympathetic dominance), and the efficacy of beta blockers in preventing orthostatic symptoms and absence of tilt-induced syncope, with normalization of the LF/HF ratio response.
