CTA’s Health, Fitness and Wellness Committee (R11) has recently launched a project to develop a standard, CTA-2141, Definitions and Use Cases for Heart Rate Variability (HRV) in Consumer Technologies, which establishes a definition of Heart Rate Variability (HRV) and outlines the range of use cases in which HRV is utilized across digital health technologies. The document will provide foundational terminology and context to support consistent usage and interpretation of HRV in digital health, wellness and related consumer domains.
