...In addition to HR, we examined HR variability (HRV), a clinically relevant diagnostic metric that can be derived from PPG signals and is a widely used metric of autonomic nervous system function.(43) The standard HRV metrics we examined, included the time-domain metrics, included mean HRV, minimum HRV, maximum HRV, RMSSD, SDNN, and pNN50 (Supplementary Fig....

...A third category of HRV is respiratory sinus arrhythmia (RSA), which reflects heart rate variations via the vagus nerve related to the respiratory cycle (Task Force of The European Society of Cardiology and The North American & Society of Pacing and Electrophysiology, 1996; Shaffer et al., 2014; Shaffer and Ginsberg, 2017)....

...Further, the literature is inconclusive regarding equivalence and the approach of treating interrelated HRV measures equivalent, in particular when measures derived from shortterm recordings (Task Force of The European Society of Cardiology and The North American & Society of Pacing and Electrophysiology, 1996; Berntson et al., 2005; Kemp et al., 2010; Shaffer and Ginsberg, 2017)....

...…sympathetic nerve activation, and the non-linear interactions between sympathetic and parasympathetic activity that are confounded by the mechanical effects of respiration and heart rate mean that the LF: HF sympatho-vagal balance hypothesis is inaccurate (Billman, 2013; Shaffer & Ginsberg, 2017)....

...Further information on heart activity related metrics can be found in detailed reviews (Jennings et al., 1981; Task Force of the European Society of Cardiology, 1996; Berntson et al., 2007; Laborde et al., 2017; Shaffer and Ginsberg, 2017)....

...For instance, some metrics require minimum duration of data and falling short of such requirements will lead to misrepresentative findings (e.g., standard deviation of R-R heart beats or SDRR is considered more accurate when calculated over 24 h vs. 5min or shorter intervals; Shaffer and Ginsberg, 2017)....

...24 h) can also lead to uncorrelated findings and some metrics are better for short term recordings than others (Shaffer and Ginsberg, 2017)....

...Non-linear measures of HRV are useful in capturing the unpredictability and dynamic nature of heart rate time-series data (Shaffer and Ginsberg, 2017)....
