A method and apparatus for reliably detecting the P-wave component in a surface electrocardiograph. An adaptive Least Means Square filter is implemented in a programmed computer and the computer receives as its inputs a digitized version of the ECG waves picked up from two discrete locations on a subject's chest wall. The LMS adaptive filter functions to accommodate the energy component of the QRS complex thereby leaving the P-wave as the paramount signal component in the filter's "error" output.
