We show you what beat-to-beat interval (BBI) data looks like, and introduce how researchers can derive HRV from BBI.
Heart rate variability, or HRV, provides a non-invasive method of approximating the Autonomic Nervous System (ANS) and can offer valuable insights into an individual’s physical and mental health.
HRV is calculated by looking at the fluctuations between individual heartbeats. The time between each consecutive heartbeat is called the R-R interval or BBI- beat to beat interval -and when using specialized platforms like Labfront, researchers are able to collect that granular BBI data from Garmin devices directly.
Learn more about HRV with our HRV Collection, which includes a master class from Dr. Andrew Ahn.
And that’s how you derive time-domain HRV from raw BBI data. To learn more about deriving HRV from BBI, please feel free to explore our resources shared below!
