RMSSD: The square root of the average of the sum differences square between the intervals R-R adjacent; LF (abs): Low Frequency component of the HRV with absolute numbers; HF (abs): High Frequency component of the HRV with absolute numbers.
The numbers 1 and 2 shown pre and post nicotine pulverized oral.
