Abstract
Intervals between two consecutive cardiac beats (R‐R intervals) and the subsequent analysis of heart rate variability (HRV) obtained simultaneously from the Polar S810 heart rate monitor (HRM) and an electrocardiogram (ECG) in a supine position were compared in twelve children (age 9.6 ± 0.9 years) before and after protocol correction. R‐R intervals were significantly different between the ECG and the HRM uncorrected and corrected signal (p < 0.001, effect size [ES] = 0.005, and 0.005, respectively). However, the bias (95% confidence interval) was 0.80 (-124.76 -123.16) ms and 0.80 (-12.76 -11.16) ms, respectively. HRV parameters derived from both signals were not different (p > 0.05) and well correlated (r > 0.99, p < 0.05), except SD2 (p < 0.05, ES = 0.000; r = 0.99). These data support the validity of the Polar S810 HRM to measure R‐R intervals and make the subsequent HRV analysis in a supine position in children. Verf.-Referat
