Reference ranges for short-term heart rate variability measures in individuals free of cardiovascular disease: The Multi-Ethnic Study of Atherosclerosis (MESA)
WT O'Neal, LY Chen, S Nazarian… - Journal of …, 2016 - Elsevier
Background Normative values for heart rate variability (HRV) measures from 10-s
electrocardiograms (ECG) have not been defined. Methods We reported borderline
abnormal (< 5th percentile) and abnormal (< 2nd percentile) values of standard deviation of
all normal-to-normal RR intervals (SDNN) and root mean square of successive differences
between normal-to-normal RR intervals (rMSSD) from 10-s ECGs in 1175 participants
(mean age= 59±10; 59% female; 47% white)≥ 45 years of age from the Multi-Ethnic Study …
