The Movesense Medical Sensor Chest Belt Device as Single Channel ECG for RR Interval Detection and HRV Analysis during Resting State and Incremental Exercise: A Cross-Sectional Validation Study

The value of heart rate variability (HRV) in the fields of health, disease, and exercise science
has been established through numerous investigations. The typical mobile-based HRV device simply
records interbeat intervals, without differentiation between noise or arrythmia as can be done with
an 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 of
21 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 for
linear indexes with Pearson’s r between 0.98 to 1.0 for meanRR, SDNN, RMSSD, and 0.95 to 0.97 for
the non-linear index DFA a1 during PRE, EX, and POST. There was no significant difference in device
specific meanRR during PRE and POST. Bland–Altman analysis showed high agreement between
devices (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 ms
during high intensity exercise). The Movesense Medical device can be used in lieu of a reference
ECG for the calculation of HRV with the potential to differentiate noise from atrial fibrillation and
represents a significant advance in both a HR and HRV recording device in a chest belt form factor
for lab-based or remote field-application.
