The aim of the present study was to assess criterion validity, and relative and absolute reliability of Polar® RS800CX heart rate monitor, compared to simultaneously recorded electrocardiogram (ECG) data, in measuring heart rate of dogs during standing position and at trot on a treadmill.
Heart beats from Polar® RS800CX and Cardiostore ECG were recorded simultaneously during seven continuous minutes in standing position and at trot, in 10 adult healthy dogs. Polar® data was statistically compared to ECG data for a variety of mean beats per minute (BPM), standard deviation and confidence interval. Criterion validity was calculated by Pearson product moment correlation method and intraclass correlation coefficient (ICC2.1). Relative and absolute reliability were calculated by ICC2.1, the Bland and Altman analysis and standard error of measurement (SEM and SEM%).
The correlation, criterion validity, between Polar® and ECG data in standing position was r = 0.99 (p < 0.0005) and at trot r = 0.97 (p < 0.0005). Polar® data was not significantly different from ECG data. Mean difference between ECG and uncorrected Polar® data was − 0.6 BPM in standing position and − 0.6 BPM at trot. Polar® was over- and underestimating ECG data. SEM and SEM% in standing were ± 2.6 BPM and 3.0%, at trot ± 3.8 BPM and 3.1%, indicating that measurement errors were low.
This study showed that the criterion validity and the instrument reliability were excellent in Polar® RS800CX heart rate measuring system. The equipment seemed to be valid and reliable in measuring BPM in the dogs studied during submaximal cardiovascular conditions such as in standing position and at trot on a treadmill.
