Agreement between Electrocardiogram and Heart Rate Meter Is Low for the Measurement of Heart Rate Variability during Exercise in Young Endurance Horses.

Abstract: Analysis of the heart rate variability (HRV) gains more and more importance in the assessment of training practice and welfare in equine industry. It relies on mathematical analyses of reliably and accurately measured variations in successive inter-beat intervals, measured as RR intervals. Nowadays, the RR intervals can be obtained through two different techniques: a heart rate meter (HRM) or an electrocardiogram (ECG). The agreement and reliability of these devices has not been fully assessed, especially for recordings during exercise. The purpose of this study was to assess the agreement of two commercially available devices using the two mentioned techniques (HRM vs ECG) for HRV analysis during a standardized exercise test. Simultaneous recordings obtained during light exercise and during canter with both devices were available for 36 horses. Data were compared using a Bland-Altman analysis and the Lin's coefficient. The agreement between the assessed HRV measures from the data obtained from the ECG and HRM was acceptable only for the mean RR interval and the mean heart rate. For the other studied measures (SDNN, root mean square of successive differences, SD1, SD2, low frequency, high frequency), the agreement between the devices was too poor for them to be considered as interchangeable in these recording conditions. The agreement tended also to be worse when speed of the exercise increased. Therefore, it is necessary to be careful when interpreting and comparing results of HRV analysis during exercise, as the results will depend upon recording devices. Furthermore, corrections and data processing included in the software of the devices affect largely the output used in the subsequent HRV analysis; this must be considered in the choice of the device.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article is focused on comparing the effectiveness and agreement of two commonly used methodologies to measure heart rate variability (HRV) in young endurance horses during exercise. The comparative study reveals that only certain measures showed acceptable agreement between the Electrocardiogram (ECG) and Heart Rate Meter (HRM) methods, with some measures showing poor agreement between the two devices, especially when exercise speed increased.

Introduction

  • The study begins with acknowledgement of the increasing importance of HRV analysis in assessing training practice and horse welfare within the equine industry.
  • The software and devices used in HRV measurement predominantly utilize two techniques, the ECG and HRM. However, their reliability and agreement have not fully been evaluated, particularly in the context of exercise.

Aim of the Study

  • The main objective of the research was to evaluate the level of agreement between HRM and ECG methods when used to analyze HRV during exercise.

Methodology

  • The research used 36 horses for the experiment. The horses were subjected to a standardized exercise protocol, during which data was collected simultaneously from both ECG and HRM devices.
  • The researchers used Bland-Altman analysis and Lin’s coefficient for the comparative analysis of the collected data.

Results & Conclusion

  • The results revealed acceptable agreement between HRM and ECG only for the mean RR interval and the mean heart rate.
  • Other parameters, such as SDNN, SD1, SD2, low frequency, high frequency, showed poor agreement, deeming the devices not interchangeable.
  • A noted trend was the decreased level of agreement as the exercise speed increased.
  • The article concludes by cautioning about the interpretation and comparison of HRV analysis results, particularly when they depend on the recording device.
  • Additionally, the paper shows that software corrections and data processing built into the devices greatly influence the output for HRV analysis. Therefore, consideration for these factors is crucial when choosing the device for HRV measurement.
