Title:
ELECTROCARDIOGRAPHY SIGNAL WAVEFORM FEATURE POINT EXTRACTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/148452
Kind Code:
A1
Abstract:
An electrocardiography signal waveform feature point extraction method, comprising QRS wave point, P wave point and T wave point position determination: processing an electrocardiography signal via a smooth wavelet transform (S2), determining a QRS wave embodiment optimal target layer and a T and P wave embodiment optimal target layer (S3), finding maximum value and minimum value pairs of the corresponding target layers (S4), removing maximum value and minimum value pairs which do not meet requirements (S5), performing error detection and miss detection on an R wave point position, obtaining a final R wave point position (S7), determining Q wave point and S wave point positions (S8), and determining P wave point and T wave point positions (S9). The QRS wave point, T wave point and P wave point position determination all use the smooth wavelet transform, and compared to a discrete wavelet transform, the smooth wavelet transform effectively avoids resolution damage during scale increasing without movement deformation, thereby effectively solving the problem in the prior art.
