High altitude-related neurocardiogenic syncope

This report presents a well-documented link between vasodepressor syncope, 5 a marked increase of LF HF ratio response to orthostasis (sympathetic dominance), 6 and the efficacy of β blockers in preventing orthostatic symptoms and absence of tilt-induced syncope, 5 with normalization of the LF HF ra...
