It is assumed that the low-frequency power (LF) of heart rate variability (HRV) increases with progress of congestive heart failure (CHF), therefore positively correlating with cardiac 123I-metaiodobenzylguanidine (MIBG) washout. It is demonstrated here that HRV, including normalized LF, correlated inversely with MIBG washout and positively with the ratio of heart-to-mediastinum MIBG activity in controls and CHF patients, whereas these correlations were not observed within CHF patients. Thus MIBG washout may increase and HRV including normalized LF may decrease with CHF, although the HRV and MIBG measures may not similarlychange in proportion to the severity of the cardiac autonomic dysfunction in CHF.rights:社団法人日本循環器学会rights:本文データは学協会の許諾に基づきCiNiiから複製したものであるrelation：isVersionOf:http://ci.nii.ac.jp/naid/110002561104
