This Paper propose a nobel method for detecting T-wave alternans (TWA) based on 3-channel Holter ECG data. The method is intended to be the core of realizing an accurate and efficient TWA detection system based on the data acquired under non-controlled common daily activity. The proposing method examines the change in T-wave morphology based on singular value decomposition (SVD). By way of comparison, Pattern of SVD to all T-wave and a T-wave. Create a character space and character series which to evaluate the usefuIness. The method has been applied to 20 normal subjects ant 24 subjects with TWA to confirm its validity. The method will be a useful tool to extract an extra important diagnostic index from the popular Holter ECG recording.
