Abstract

The invention provides an intelligent detection unit, method and system capable of extracting a PACE wave. The intelligent detection unit capable of extracting the PACE wave comprises a digital filtering unit, an edge reinforcing and sharpening unit, a PACE wave shape similarity extracting unit and a PACE wave characteristic parameter extracting unit, wherein the digital filtering unit is used for filtering high-frequency and low-frequency noise in a PACE wave digital signal, the edge reinforcing and sharpening unit is used for conducting steepening processing on a rising edge / a falling edge of the PACE wave digital signal which is filtered, restraining low-frequency components and enabling the edge of the signal to be steeper, and the PACE wave characteristic parameter extracting unit is used for extracting PACE wave characteristic parameters out of the detected PACE wave digital signal. The intelligent detection unit, method and system capable of extracting the PACE wave has the advantages that the intelligent detection unit is stable in performance and can extract the PACE wave out of the interfered signal, work efficiency is improved, and a user can conveniently conduct using.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an intelligent detection unit, method and system for extracting PACE waves. Background technique [0002] In some patients, the heartbeat is triggered by a pacemaker. The electrical pulse (ie PACE wave) generated by the pacemaker is detected by the measurement circuit along with the body's own physiological signal. The aliasing effect of this signal will affect the heart rate. Signal measurement; when the PACE wave amplitude is large, the PACE wave will also be modulated onto the respiratory wave, affecting the respiratory waveform. [0003] During the use of medical equipment, it may be affected by interference sources such as high-frequency electric scalpel and power frequency. These interference sources are very likely to generate signals similar to PACE characteristics, and false PACE phenomenon will appear. In order to ensure the accuracy of ECG and respiration measurement,...
