The Pulse of Precision: Assessing the Validity of Mobile Heart Rate Variability Monitoring 1. Introduction
In a scientific context, "Heart" likely refers to —a popular non-invasive biomarker for autonomic nervous system function. " Validity " is a critical research concept that measures whether a tool (like a smartphone app) accurately reflects a person's true physiological state compared to a "gold standard".
