Low frequency power of heart rate variability reflects baroreflex function, not cardiac sympathetic innervation
Background Power spectral analysis of heart rate variability is used to assess cardiac autonomic function. The relationship of low frequency (LF) power to cardiac sympathetic tone has been unclear. We reported previously that LF power may reflect baroreflex modulation. In this study we attempted to...

description | Background
Power spectral analysis of heart rate variability is used to assess cardiac autonomic function. The relationship of low frequency (LF) power to cardiac sympathetic tone has been unclear. We reported previously that LF power may reflect baroreflex modulation. In this study we attempted to replicate our findings in additional subject cohorts, taking into account possible influences of respiration and using different methods to measure baroreflex-cardiovagal gain (BCG).
Objective
We assessed relationships of LF power, including respiration-adjusted LF power (LFa), with cardiac sympathetic innervation and baroreflex function in subjects with or without neuroimaging evidence of cardiac sympathetic denervation.
Methods
Values for LF power at baseline supine, seated, and during the Valsalva maneuver were compared between subject groups with low or normal myocardial concentrations of 6-[
18
F]fluorodopamine-derived radioactivity. BCG was calculated from the slope of cardiac interbeat interval vs. systolic pressure during Phase II of the Valsalva maneuver or after i.v. nitroglycerine injection (the Oxford technique).
Results
LF and LFa were unrelated to myocardial 6-[
18
F]fluorodopamine-derived radioactivity. During sitting rest and the Valsalva maneuver logs of LF and LFa correlated positively with the log of Phase II BCG (

LF power, with or without respiratory adjustment, reflects baroreflex modulation and not cardiac sympathetic tone.</description><identifier>ISSN: 0959-9851</identifier><identifier>EISSN: 1619-1560</identifier><identifier>DOI: 10.1007/s10286-010-0098-y</identifier><identifier>PMID: 21279414</identifier><identifier>CODEN: CAURE9</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer-Verlag</publisher><subject>Baroreflex - physiology ; Cardiology ; Case-Control Studies ; Diabetes ; Electrophysiologic Techniques, Cardiac - methods ; Endocrinology ; Gastroenterology ; Heart - innervation ; Heart - physiology ; Heart Rate - drug effects ; Heart Rate - physiology ; Humans ; Hypotension, Orthostatic - physiopathology ; Medicine ; Medicine & Public Health ; Multiple System Atrophy - physiopathology ; Neurology ; Nitroglycerin - pharmacology ; Ophthalmology ; Parkinson Disease - physiopathology ; Pure Autonomic Failure - physiopathology ; Research Article ; Sympathetic Nervous System - physiology ; Tomography, Emission-Computed ; Valsalva Maneuver - physiology ; Vasodilator Agents - pharmacology</subject><ispartof>Clinical autonomic research, 2011-06, Vol.21 (3), p.133-141</ispartof><rights>Springer-Verlag (outside the USA) 2011</rights><rights>Springer-Verlag 2011</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c445t-4630aa13816de5162314aca1c87b6b345efd4b0cfd580a36318ad1e8617716a53</citedby><cites>FETCH-LOGICAL-c445t-4630aa13816de5162314aca1c87b6b345efd4b0cfd580a36318ad1e8617716a53</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/21279414$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Rahman, Faisal</creatorcontrib><creatorcontrib>Pechnik, Sandra</creatorcontrib><creatorcontrib>Gross, Daniel</creatorcontrib><creatorcontrib>Sewell, LaToya</creatorcontrib><creatorcontrib>Goldstein, David S.</creatorcontrib><title>Low frequency power of heart rate variability reflects baroreflex function, not cardiac sympathetic innervation</title><title>Clinical autonomic research</title><addtitle>Clin Auton Res</addtitle><addtitle>Clin Auton Res</addtitle><description>Background
