Adaptive recurrent filter for ectopic beat and arrhythmia detection
Y.-S. Zhu, Nitish V. Thakor · Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society · 1988
The electrocardiogram is characterized by a well-defined morphology of signal complexes, e.g. the P-QRS-T sequence that recurs with each heart beat. The adaptive recurrent filter is useful for learning the morphology of the signal complexes and for detecting transient variations. The authors present application of the ARF to 60-Hz power-line cancellation, P-wave detection in conduction blocks, recognition of atrial fibrillation and paced rhythm, and detection of ectopic beats.>
