Key result
One-minute HRV sampling during tilt table testing lacks published outcome data.
Why the study?

One-minute sampling windows for heart rate variability may provide a method to detect rapid autonomic nervous system changes during tilt table testing.
background: The autonomic nervous system (ANS) responds rapidly to homeostatic perturbations. Heart rate variability (HRV) analysis can give insights into autonomic balance but traditionally sampling windows of five minutes or more have been employed, thus making HRV insensitive to sudden changes. We sought to determine whether one minute sampling windows could be used to detect rapid changes in ANS activity during tilt table testing (TTT).

Hayward et al. (2015) conducted an observational in Autonomic nervous system activity during tilt table testing. One minute sampling windows for heart rate variability analysis vs. Traditional sampling windows of five minutes or more was evaluated on Detection of rapid changes in autonomic nervous system activity. The abstract only describes the study objective to evaluate one-minute sampling windows for heart rate variability during tilt table testing, without reporting any results.
