Abstract

BACKGROUND: A Polar heart rate monitor is a device that measures RR intervals, but has not been correlated to accurately measure the series of RR interval signals between the ECG and the Polar® Heart Rate Monitor Interface (HRMI) Board at rest. OBJECTIVE: The aim of the study was to evaluate the temporal cross-correlations between the Polar® HRMI Board and an ECG to measure the series of RR intervals at rest. METHODS: The sample consisted of eighteen healthy male subjects and they were instructed to lie in the supine position at rest while breathing normally and a time window of the last 2 min was recorded to analyse RR intervals were obtained for each subject with a Polar® HRMI Board and an ECG. Cross-correlation analysis of RR interval signals between methods and reliability was expressed by Bland and Altman analysis. RESULTS: The cross-correlation was excellent, resulting in a mean of 0.98 ± 0.01 and no lag or delay between the signals. The bias was 0.03 ± 0.08 s or 8.0% for MeanRRi from Polar® HRMI Board and ECG, no significant difference. CONCLUSIONS: The Polar® HRMI Board is acceptable for assessment of serial RR intervals. The results support the reliability of the Mean RR interval compared to a resting ECG.

Polar®心率监测仪接口板与ECG之间的时间相互关联，以测量静息时的RR间期

背景：Polar心率监测器是一种测量RR间期的设备，但尚未与静息时心电图和Polar®心率监测器接口（HRMI）板之间的一系列RR间期信号相关联。目的：本研究的目的是评估Polar®HRMI板和心电图之间的时间交叉相关性，以测量休息时的一系列RR间期。方法：样本由18名健康男性受试者组成，他们被要求在休息时仰卧，同时正常呼吸，并记录最后2分钟的时间窗口以分析每个受试者的RR间期。采用Bland和Altman分析法对方法间RR间期信号与可靠性进行互相关分析。结果：互相关良好，平均值为0.98±0.01，信号之间没有滞后或延迟。Polar®HRMI Board和ECG的MeanRRi的偏差为0.03±0.08s或8.0%，无显著差异。结论：Polar®HRMI委员会可用于评估系列RR间期。结果支持平均RR间期与静息心电图相比的可靠性。

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
