摘要
This report presents a well-documented link between vasodepressor syncope, a marked increase of low-frequency to high-frequency ratio (LF/HF) of heart rate variability 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.
