PROBLEM TO BE SOLVED: To provide an arithmetic unit, a heart arrhythmia evaluation method using the same, and a non-transitory computer-readable recording medium incorporating a plurality of symptoms for heart arrhythmia evaluation.SOLUTION: There are provided an arithmetic unit, a heart arrhythmia evaluation method using the same, and a non-transitory computer-readable recording medium. By the method, an electrocardiogram (ECG) signal is obtained. It is determined whether or not the ECG signal conforms to a first abnormal rhythm symptom. Then, based on the determination result on the first abnormal rhythm symptom, it is determined whether or not the ECG signal conforms to a second abnormal rhythm symptom different from the first abnormal rhythm symptom. Therefore, a plurality of abnormal rhythm evaluations are integrated, and using previous evaluation results, subsequent evaluations can be accelerated or optimized. The present invention can be achieved on a portable device.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT
