Implication

Supports feasibility of automated HRV analysis during activity; leaves open prospective clinical validation.

Key Points

To develop and validate automated algorithms capable of detecting and correcting inter-heartbeat interval errors in real time during active physical movement.
Recorded 124,998 inter-heartbeat intervals from N=18 individuals participating in diverse physical motions outside a controlled setting.
Engaged two independent human graders to label each interval manually to identify errors and establish a reference standard.
Tested an automated algorithmic framework against human consensus to measure detection agreement, correction accuracy, and false positive rates.
Human annotators identified movement-related errors in 10% of all evaluated inter-heartbeat intervals.
The automated algorithm achieved a 96% agreement rate with the human annotators when both graders concurred on an error.
The method matched specific human error corrections at a 49% rate while maintaining a 0.01% false alarm rate.
