A telemeter and garment-type electrode to measure heart rate variability (HRV) and perform analysis based on the R-R interval (RRI) of electrocardiograms (ECGs) were developed to improve the detection of cardiac disease. The optimum electrode arrangement depends on individual differences such as the patient's physique. To solve this problem, a garment-type textile electrode and telemeter were developed; these can select an optimal induction from four different choices to measure RRI. In this study, the R-wave detection rate and system reliability were evaluated by comparing the RRIs of the telemeter and signals from the reference ECG measurement system. Results show that the system provides sufficient RRI measurement accuracy for HRV analysis.
为了改善心脏病的检测，研发了一种用于测量心率变异性（HRV）并基于心电图（ECG）的R-R间期（RRI）进行分析的遥测仪和服装式电极。最佳电极布置取决于个体差异，如患者的体格。为了解决这个问题，开发了一种服装式纺织电极和遥测仪；它们可以从四种不同选择中选择最佳感应方式来测量RRI。在本研究中，通过比较遥测仪的RRI和来自参考ECG测量系统的信号，评估了R波检测率和系统可靠性。结果表明，该系统为HRV分析提供了足够的RRI测量精度。
