Abstract:
1. A T-wave alternans (TWA) measuring apparatus comprising: a T-wave feature quantity measuring section which is configured to measure T-wave feature quantities of electrocardiogram waveforms acquired from a subject; a classifying section which is configured to classify the T-wave feature quantities into a group of odd electrocardiogram waveforms and a group of even electrocardiogram waveforms; a reliability index calculating section which is configured to calculate: a reliability recognizing section which is configured to recognize: an output section configured to output the TWA feature quantity and the reliability index, wherein the reliability index calculating section calculates: wherein the reliability index calculating section calculates a difference between the first difference value and the first sum value, to obtain the reliability index, wherein the T-wave quantity measuring section, the classifying section, the reliability index section, and the reliability recognizing section, are executed by a processor.
