Problems solved by technology

The other 120-plus types of leads are still not comparable to the 12-lead system
However, since 12 leads need to place 10 electrodes on the human body surface, they are left hand (LA), right hand (RA), left foot (LF) and right foot (RF) and six chest leads (V 1 —V 6 ), in medical practice, it is easy for nurses to place electrodes in the wrong position, resulting in inaccurate test results

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0040] The hardware of the present invention is consistent with that of a common 12-lead electrocardiometer, and the judgment is made by using the waveform feature quantity intercepted by the conventional 12-lead electrocardiogram waveform, including:

[0041] (1) P wave electric axis, the unit is radian, if there is no P wave, it will be calculated as zero value, and the variable x 1 express;

[0042] (2) The effective amplitude of the P wave in lead I, where the net amplitude of the P and T waves is the absolute value of the maximum positive peak amplitude minus the maximum negative peak amplitude, in millivolts, and zero if there is no P wave Compute, with variable x 2 express;

[0043] (3) The effective amplitude of the P wave in lead V6, in millivolts, if there is no P wave, it will be calculated as zero, and the variable x 3 express;...

Abstract

The invention discloses an automatic detection method used for wrong placement of electrocardio-electrodes and based on a kernel function classification algorithm. Due to the automatic detection method, placement of arm and foot electrodes in wrong positions is detected intelligently by equipment without additional assistance. According to the method, reference signals are divided into seven categories and an arbitrary given electrocardial vector is identified and classified with a classifier method based on a kernel function; and abnormal waveform caused by heart disease and wrong placement can be discriminated accurately, and the electrocardiogram analysis accuracy is improved greatly.

Description

technical field [0001] The invention relates to a biological signal processing method, which belongs to the field of information science and engineering. Background technique [0002] Heart disease is a major disease that kills human beings. Human electrocardiogram, as a comprehensive manifestation of the electrical activity of the heart on the body surface, contains a wealth of physiological and pathological information reflecting the heart rhythm and its electrical conduction. However, due to the wide variety and great variation of pathological ECG, it is necessary to have rich professional knowledge and clinical experience to make accurate judgments. Portable electrocardiographs currently on the market use 2 or 3 leads, which cannot reflect the whole picture of the heart's electrical activity, and cannot accurately locate changes in the electrocardiogram such as acute myocardial infarction, atrioventricular hypertrophy, and bundle branch block. The positive rate is also ...
