Key result
Comparison of RRi and ECG file types for infant heart rate variability analysis revealed significant differences in root mean squared successive differences between recording types.
Why the study?
Reliable HRV recordings are vital to understand autonomic response in infants, but no protocol exists.
Does the file type (RRi vs ECG) affect the analysis of heart rate variability in infants?
Does the file type (RRi vs ECG) affect the analysis of heart rate variability in infants?
Differences exist between HRV analysis procedures using RRi versus ECG files in infants, highlighting the need for standard methodology.
Offers reliable infant HRV protocol at 1 month; leaves open validation before clinical or research adoption.
Heart rate (HR) and heart rate variability (HRV) reflect autonomic development in infants. To better understand the autonomic response in infants, reliable HRV recordings are vital, yet no protocol exists. The purpose of this paper is to present reliability of a common procedure for analysis from two different file types. In the procedure, continuous electrocardiograph recordings of 5-10 min are obtained at rest in infants at 1 month of age by using a Hexoskin Shirt-Junior's (Carre Technologies Inc., Montreal, QC, Canada). Electrocardiograph (ECG; .wav) and R-R interval (RRi; .csv) files are extracted. The RRi of the ECG signal is generated by VivoSense (Great Lakes NeuroTechnologies, Independence, OH). Two MATLAB (The MathWorks, Inc., Natick, MA) scripts converted files for analysis with Kubios HRV Premium (Kubios Oy, Kuopio, Finland). A comparison was made between RRi and ECG files for HR and HRV parameters, and then tested with t tests and correlations via SPSS. There are significant differences in root mean squared successive differences between recording types, with only HR and low-frequency measures significantly correlated together. Recording with Hexoskin and analysis with MATLAB and Kubios enable infant HRV analysis. Differences in outcomes exist between procedures, and standard methodology for infant HR analysis is needed.

Claiborne et al. (2023) studied Autonomic development. RRi (.csv) files vs. ECG (.wav) files was evaluated on HR and HRV parameters (including root mean squared successive differences). Comparison of RRi and ECG file types for infant heart rate variability analysis revealed significant differences in root mean squared successive differences between recording types.
