LF: Low frequency; HF: High frequency; LF/HF: Low frequency/High frequency ratio; SDNN: standard deviation of normal-to-normal R-R intervals; pNN50: percentage of adjacent RR intervals with a difference of duration greater than 50 ms; RMSSD: root-mean square of differences between adjacent normal RR intervals in a time interval. Mean ± Standard Deviation. ms: milliseconds; mmHg: millimeters of mercury.
