Abstract
Objective: To validate a single-lead ECG fitness tracker device (FT) against the reference multilead ECG recording device (RM) for heart rate (HR) and HR variability (HRV) monitoring of horses during routine swimming.
Methods: 40 race-fit Thoroughbred racehorses were used for 5 days in May 2024. Surface ECG recordings were obtained simultaneously from the FT and RM devices in horses swimming 63.65 m across a pool. Electrocardiograms were reviewed and artifacts corrected when necessary, and correlations were analyzed between the 2 devices for HR and HRV parameters. Descriptive statistics and Bland-Altman tests were used to determine the agreement between data generated from the 2 devices.
Results: A negligible bias was observed for HR (r = 0.99) between the 2 devices. The root mean squared error calculated for HR between them was 0.28 beats/min. The time domain and nonlinear HRV parameters, except triangular index, had additional variability and bias with the FT compared to the RM. This suggests that additional testing is needed to validate the FT for assessment of HRV parameters.
Conclusions: The FT and the RM can be used interchangeably for HR monitoring in swimming horses. The FT is not recommended for comprehensive HRV analysis during swimming before bias and variability are corrected.
Clinical relevance: Our findings confirm that the FT is a practical tool to reliably monitor HR in swimming horses, which has applications for fitness and workload monitoring during training.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
