Ultra-Short-Term (UST) HRV Measurements Can Achieve Strong Concurrent Validity

This within-subjects study investigated whether artifacted resting ultra-short-term (UST) heart rate variability (HRV) values can achieve strong concurrent validity for time domain, frequency domain, and nonlinear measurements in healthy undergraduates when compared to 5-min resting baseline values. A Thought Technology ProComp™ Infiniti system monitored ECG and respiration. Subjects were stabilized for 5 min and then monitored for 7 min sitting upright, with eyes open, no feedback, and instructions to breathe normally. The investigators extracted 10-, 20-, 30-, 60-, 90-, 120-, 180-, and 240-s segments from 5-min resting ECG recordings of 38 healthy undergraduates, 20 men and 18 women, ages 18 to 23. Concurrent validity between the UST and 5-min measurements were measured using a Pearson Product-Moment Correlation Coefficient. A conservative criterion (r = .90) was selected. Resting UST measurements achieved strong concurrent validity for all but one of the 5-min HRV metrics examined in this study.
