Also, there was a significant decrease of SDNN and RMSSD in response to painful stimuli (SDNN: F = 6.
Therefore, we considered the association to be unstable and do not report results for RMSSD here.
RMSSD (square root ms The square root of the mean of the of the mean squared sum of the squares of differences differences of between adjacent NN intervals.
2]), m--male, nuHF--HF power in normalized units (nuHF=HF/HF+LF), nuLF-LF power in normalized units (nuLF=LF/HF+LF), RMSSD (ms)--the square root of the mean of the sum of the squares of differences between adjacent NN intervals, SDANN (ms)-standard deviation of the averages of NN intervals in all 5 min segments of the entire recording, SDNN (ms)-standard deviation of all NN intervals, SDNN index (ms)-mean of the standard deviations of all NN intervals for all 5 min segments of the entire recording, this variant is possible counting all such NN intervals pairs or only pairs in which the first or the second interval is longer, TP--total power ([ms.

2010) demonstrated that air-pollution-induced increases in arrhythmias were linked with increased RMSSD.

We observed the largest difference with adjustment for RMSSD (RR = 1.
The evaluations of TRABI for the indices SDRR, RMSSD and LF/HF are lower in patients with MMI.
