title: Adaptive fiducial point detector for ECG stress testing systems.
abstract: The paper deals with the problem of fiducial point detection in noisy exercise ECG signals. Performance of the averaging process depends on the detector's repeatability. The paper proposes an adaptive algorithm for optimization of the detector. The structure of the detector is well known and often used. Characteristics of the last filter are matched to the current signal and bandpass filter impulse response. The new method was tested using real ECG signals. Results indicated that the FP jittering was reduced to almost one half.
