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
