抄録: This paper proposes a method of cardiac risk assessment based on a long-term ECG records. The risk assessment is important because the sudden cardiac death is the major cause of death worldwide. It has been reported that the annual number of death is 20,000-30,000 in Japan and 300,000 in the U.S. The common known indices such as QT/ST length are derived from a short-term ECG record at the clinical laboratory in the hospital. It is preferable if they are obtained from the ECG data in daily life using IoT or wearable device. In this research direction indices based on the long-term Holter ECG record has been proposed. This paper focuses the use of T-wave alternans estimated from 24 hour Holter ECG record for the cardia risk assessment. The new risk index named T-wave alternans percentile has been defined and its usefulness has been examined. The robustness against the recording artifact is an important feature for the system utilized in noisy daily environment. It has been shown that the new index is robust in classifying the different risk patient groups and control subjects. Keywords: Cardiac risk assessment, T-wave alternans, Holter ECG record, singular value decomposition
