High-quality human heart rate variability (HRV) data of immersive virtual reality session

The data incorporate heart rate variability (HRV) records collected in 15 healthy participants (7 women) in two sets (background and orthostatic) before and right after a 20-min session in immersive virtual reality. Measurements include the Mean HR — average heart rate; SDNN — standard deviation of all normal RR intervals in ms corresponding to the global heart rate variability; RMSSD — the root-mean-square of the differences between adjacent normal RR intervals in a time interval, expressed in ms, representing parasympathetic activity; the LF index — low-frequency component reflecting the global action (vagal and sympathetic components) on the heart with a predominance of the sympathetic, including variations between 0.04 and 0.15 Hz; HF — high-frequency component indicating the action of the vagus nerve on the heart, including variations from 0.15 to 0.4 Hz; the LF/HF ratio — the relationship between these two indices, reflecting the sympathovagal balance; Baevsky Stress Index, and others. A total of 4,320 high-quality HRV records (288 for each participant) are provided.
