Detection of the P- wave within associated noise and other background signals is difficult. An Adaptive Correlating Filter has been developed to solve this problem.<BR>The adaptive property of this filter arises from its iterative correlation and averaging of data, making possible recognition of specific waveforms not known in advance. Its statistical property makes it useful for practical ECG processing in the identification and resolution of the P-wave. The procedure of P-wave segmentation, which is required before using this filter, is also discussed.<BR>The filter has helped identify a P-wave with a low signal-to-noise ratio. It has also proved useful in the case of arrhythmia, such as complete A-V block where the P-wave overlaps the QRS complex and the T-wave.<BR>This method should be useful for P-wave recognition in ECG auto-analysis of arrhythmia.
