Why the study?
Does 24-hour heart rate variability analysis differentiate autonomic profiles in patients with vasovagal syncope?
Does 24-hour heart rate variability analysis differentiate autonomic profiles in patients with vasovagal syncope?
24-hour heart rate variability analysis, specifically SDANN, can identify distinct autonomic profiles in patients with vasovagal syncope, differentiating vasodepressive from cardioinhibitory responses.
No takes yet. Share an insight, caveat, or question.
SDANN <100 ms may distinguish vasodepressive syncope; hypothesis-generating for HRV subtyping, pending prospective validation.
Lazzeri et al. (2000) studied this question.
