Effects of Data Compression on the P-wave Recognition with the Adaptive Correlating Filter
Effects of data compression, to save the processing time in the P-wave recognition program with the adaptive correlating filter (ACF), on the performance of the ACF has been studied.All QRS or QRST regions were eliminated from the record to compress ECG data. Two indices were adopted as criteria for...

| description | Effects of data compression, to save the processing time in the P-wave recognition program with the adaptive correlating filter (ACF), on the performance of the ACF has been studied.All QRS or QRST regions were eliminated from the record to compress ECG data. Two indices were adopted as criteria for evaluating the effects. One was derived on the basis of the performance characteristics of the ACF, while the other was the mean error probability in detecting P-waves by using the ACF. In result, it was shown that the method for data compression could make up for the loss of the P-wave information caused by the data reduction. So the data reduction proposed here makes data compression feasible with little deterioration of the ACF performance. |
