The aims of the present study are to examine the reliability and validity of the Heart Rate signal registered using two self-made wireless ECG systems, R-Tips and TipsShirt, and to compare them with another commercial ECG device typically used in psychophysiology studies. An ECG simulator was used to artificially generate signals corresponding to different cardiac frequencies. Results of the reliability study showed that the signal acquisition, signal processing and signal transmission were reliable and valid for R-Tips and TipsShirt. Consequently, these wireless ECG prototypes could be used for studies where the freedom of movements of the participants is fundamental without any loss of quality in the registered signals.
本研究的目的是检验使用两个自制无线心电图系统R-Tips和TipsShirt记录的心率信号的可靠性和有效性，并将它们与心理生理学研究中常用的另一种商用心电图设备进行比较。使用心电图模拟器人工生成对应于不同心率的信号。可靠性研究结果表明，R-Tips和TipsShirt的信号采集、信号处理和信号传输是可靠且有效的。因此，这些无线心电图原型可用于参与者行动自由至关重要且记录信号质量无任何损失的研究。
