This paper introduces the concept of an online medical diagnosis system for ubiquitous health care using a wireless ECG sensor. To confirm the feasibility ofthe system, we conducted clinical tests by 67 subjects with a wireless ECG sensor and a Holter ECG monitor simultaneously for comparison purpose. We made five types of evaluations such as analyses on data loss rate, burst data loss length, ECG waveforms comparison, normalized cross-correlation and heart rate variability (HRV) by RR50. The results show that, as long as the sensed data are successfully received at a receiver, the wireless ECG sensor has a comparable performance with the Holter ECG monitor.
本文介绍了一种使用无线心电图传感器实现普适医疗保健的在线医学诊断系统的概念。为了确认该系统的可行性，我们让67名受试者同时使用无线心电图传感器和动态心电图监测仪进行临床测试以作比较。我们进行了五种类型的评估，如数据丢失率分析、突发数据丢失长度分析、心电图波形比较、归一化互相关分析以及基于RR间期差值的心率变异性（HRV）分析。结果表明，只要在接收器处成功接收到传感数据，无线心电图传感器就具有与动态心电图监测仪相当的性能。
