    • A heart-rate measuring apparatus is provided a database, acquisition unit, production unit, search unit, cross-correlation processing unit, and calculation unit. In the database, one or more sets of electrocardiogram (ECG) waveform data, serving as reference waveform data, of persons being examined are stored in advance. The acquisition unit acquires a heartbeat signal from a person being examined. The production unit produces ECG waveform data based on the acquired heartbeat signal. On the basis of the produced ECG waveform data, the search unit searches the database for reference waveform data of the person. The cross-correlation processing unit performs cross-correlation processing between the produced ECG waveform data and the searched reference waveform data, and the calculation unit calculates the heart rate based on the cross-correlated ECG waveform data using values of R-R intervals of the waveform.
    • 心率测量装置设置有数据库,采集单元,生产单元,搜索单元,互相关处理单元和计算单元。 在数据库中,预先存储作为被检查者的作为参考波形数据的一组或多组心电图(ECG)波形数据。 采集单元从被检查者获取心跳信号。 生产单元根据获取的心跳信号产生ECG波形数据。 在产生的ECG波形数据的基础上,搜索单元在数据库中搜索人的参考波形数据。 互相关处理单元进行所生成的ECG波形数据与检索出的基准波形数据之间的互相关处理,运算单元使用波形的R-R间隔值,根据相互关联的ECG波形数据计算心率。
