SDNN: Standard deviation of all NN interval; RMSSD: Standard deviation of
differences between adjacent NN, square root of the mean of the sum of the square
of the differences between adjacent NN intervals; pNN50: Number of adjacent NN
intervals differing by more than 50 ms divided by the total number of all NN intervals;
Mean RR: Mean RR intervals; Mean HR: Mean Heart Rate; TINN: Triangular
Interpolation of NN Interval |
