Abstract

The invention discloses a method for outputting vectorcardiogram through conventional lead, which comprises the following steps of: placing an electrode slice at a preset position on the body surfaceof a testee based on Wilson lead, and acquiring body surface electric signals of the testee; carrying out bidirectional filtering processing on the collected body surface electric signals, and drawinga conventional 12-lead electrocardiogram waveform; respectively drawing frontal plane, sagittal plane and transverse plane vectorcardiograms according to the I, aVF, V2 and V6 leads; and according tothe obtained sagittal plane vectorcardiogram, obtaining a vertical projection distance of each tear point of the sagittal plane vectorcardiogram on the corresponding virtual sagittal plane lead axis,and deriving a sagittal plane lead electrocardiogram in accordance with a tear point generation sequence. According to the invention, conventional electrocardiogram leads are utilized to obtain vectorcardiograms of three planes, the operation of the vectorcardiograms is simplified, so that the vectorcardiograms are highly matched with a conventional electrocardiogram, the problem of data deviation caused by deriving Frank lead from the conventional lead through mathematical conversion is avoided, and meanwhile, the defect that the electrical activity change of the heart on the sagittal planecannot be observed by the conventional electrocardiogram can be overcome.

Description

technical field [0001] The invention relates to the technical field of electrocardiographic signal output, in particular to a method for outputting a vector electrocardiogram by conventional leads. Background technique [0002] The electrocardiogram refers to the heart in each cardiac cycle, the various parts of the heart are excited one after another, accompanied by the change of the bioelectricity of the electrocardiogram, and the graphics of various forms of potential changes (abbreviated as ECG) are drawn from the body surface through the electrocardiograph. The electrocardiogram is It is an objective indicator of cardiac bioelectricity generation, propagation and recovery process in the heart. The ECG mainly reflects the difference in the direction and size of the electrical excitation of the heart at each moment. It is a special inspection that records the three-dimensional direction and size of the electrical excitation generated by the heart at each moment. It can m...
