【摘要】 目的研究不同个体之间心电信号的惟一性特征。方法随机挑选100份同步12导联心电图进行描述分析,对比相同点及不同点,将每份心电图的波形特征逐一输入Excel电子表格,按照波形特征顺序进行排序。结果Ⅰ导联共有25例4组重复。在这些重复的病例中:Ⅱ导联共有25例7组重复,Ⅲ导联共有24例8组重复,avR导联共有20例6组重复,avL导联共有3例1组重复,avF导联共有3例1组重复,100例中无任何两例心电波形在12个导联上完全相同。结论心电信号具有生物特征的惟一性,可作为一种新的生物特征识别方法用于身份识别。更多还原

【Abstract】 Objective To study the exclusive characteristics of electrocardiogram signal from 100 individuals.Methods Twelve-lead surface electrocardiograms were randomly selected and compared among these subjects.The characteristics of the electrocardiogram were registrated using Excel software.Compared study was performed subsequently.Results Four same ECG groups were found in 25 individuals according toⅠ-lead ECG characteristics.Seven same ECG groups were found in 25 individuals according to Ⅱ-lead ECG characteristics.Eight same ECG groups were detected in 24 individuals according to Ⅲ-lead ECG characteristics.Six same ECG groups were found in 20 individuals according to avR-lead ECG characteristics.One same ECG group was seen in 3 individuals according to avL-lead ECG characteristics.One same ECG group was observed in 3 individuals according to avF-lead ECG characteristics.Neither the same ECG was found between any two individuals in twelve-lead surface electrocardiograms.Conclusion ECG signal shows the exclusive characteristics. It could be used to recognize individual identification as a kind of new approach in biometrics.更多还原
