概要: We proposed the new digital filter algorithm for reduced noise of electrocardiogram (ECG) derived from the head. The proposed algorithm is based on the estimation technique of noise from one beat of ECG during exercise. The … estimated noise is updated by 50% of noise derived from the latest beat and 50% of the noise derived from accumulated beat. The updated noise is devoted to ECG for detection of R-peak in next beat. In 3 healthy male participants, stationary state and 40, 50 W loads exercise using cycle ergometer for 30 seconds was performed, respectively. The results indicate that noise of ECG derived from head is decreased. In conclusion, these findings suggested that the proposed adaptive filter might be practical signal processing for reduced noise of ECG derived from head. 続きを見る
