Description:
The value of heart rate variability (HRV) in the fields of health, disease, and exercise sciencehas been established through numerous investigations. The typical mobile-based HRV device simplyrecords interbeat intervals, without differentiation between noise or arrythmia as can be done withan electrocardiogram (ECG). The intent of this report is to validate a new single channel ECG device,the Movesense Medical sensor, against a conventional 12 channel ECG. A heterogeneous group of21 participants performed an incremental cycling ramp to failure with measurements of HRV, before(PRE), during (EX), and after (POST). Results showed excellent correlations between devices forlinear indexes with Pearson’s r between 0.98 to 1.0 for meanRR, SDNN, RMSSD, and 0.95 to 0.97 forthe non-linear index DFA a1 during PRE, EX, and POST. There was no significant difference in devicespecific meanRR during PRE and POST. Bland–Altman analysis showed high agreement betweendevices (PRE and POST: meanRR bias of 0.0 and 0.4 ms, LOA of 1.9 to −1.8 ms and 2.3 to −1.5; EX:meanRR bias of 11.2 to 6.0 ms; LOA of 29.8 to −7.4 ms during low intensity exercise and 8.5 to 3.5 msduring high intensity exercise). The Movesense Medical device can be used in lieu of a referenceECG for the calculation of HRV with the potential to differentiate noise from atrial fibrillation andrepresents a significant advance in both a HR and HRV recording device in a chest belt form factorfor lab-based or remote field-application.
