PROBLEM TO BE SOLVED: To restrain fluctuation of ECG signal for every cardiac beat by recording a signal sample in the form of matrix, and applying the processing for minimizing the distance between the measurement matrix and reference matrix. SOLUTION: A recording analysis device for inputting the ECG signal measured by an electrode 2 set onto a patient 3 is provided with an amplifier 4, filter and A/D convertor 8, and an arithmetic unit 10. In the unit 10, a signal sample is made to be stored in a memory means 11 in the form of m*p matrix, where (m) is the number of sample, (p) is the number led from the measurement electrode applied to the patient 3, and the analysis of sampled ECG signal is carried out. The difference between the measurement matrix and reference matrix is made minimum through operation of parallel movement, with the operation of synchronization, scaling, etc., to restrain the fluctuation in the ECG signal. |
