| SDNN | SDANN | RMSSD | HRVTrilnd | |
|---|---|---|---|---|
| C-11 HED retention (absolute) | 0.299 (n = 16) | 0.225 (n = 16) | 0.144 (n = 16) | 0.437 (n = 16) |
| Inhomogeneity | 0.393 (n = 16) | 0.228 (n = 16) | 0.293 (n = 16) | 0.5084-150
(n = 16) |
↵4-150 p < 0.05.
SDNN, standard deviation of all R-R intervals over 24 hours; SDANN, standard deviation of the mean R-R interval for all five minute segments of a 24 hour recording; HRVTrilnd, heart rate variability triangular index; RMSSD, square root of the mean of the sum of the squares of differences between adjacent NN intervals.
