A method for automatically adjusting the baseline output position for multi-channel ECG waveform drawing

Abstract

The invention provides a method for automatically adjusting a baseline output position in drawing of a multichannel electrocardiogram waveform. The method comprises the following steps of calculating out an electrocardiogram waveform voltage amplitude An which is acquired by each acquisition channel; distributing an electrocardiogram waveform drawing spatial height Hn to each channel; calculating the electrocardiogram waveform baseline value MEANn of each channel; and calculating out an electrocardiogram waveform baseline arrangement position BASELINEn, calculating the maximal value, the least value and the baseline position value of the electrocardiogram waveform of each channel, calculating out the electrocardiogram waveform baseline arrangement position in the respective area of each output channel waveform, and automatically adjusting the baseline output position of the electrocardiogram waveform for ensuring a fact that the electrocardiogram waveform is arranged at the central position of the respective area. The method is advantageous in that the electrocardiogram waveform is sufficiently utilized for drawing the area space; on condition that the electrocardiogram waveform gain is not adjusted as possible, waveform boundary exceeding and intersection are prevented for realizing reasonable arrangement and proper gain of the electrocardiogram waveform; and furthermore an attractive electrocardiogram which is obtained through the method facilitates reading by a doctor.

Description

technical field [0001] The invention relates to a method for drawing multi-channel electrocardiogram waveforms and automatically adjusting baseline output positions. Background technique [0002] The electrocardiogram machine is a physiological function detection instrument that records the waveform of the heart's bioelectric activity (ie, the electrocardiogram). It can provide basic information for the diagnosis and treatment of various heart diseases, help analyze and understand various arrhythmias, and diagnose various cardiovascular diseases. It helps to understand pathology such as certain drugs and electrolyte disturbances and the impact of acid-base imbalances on the myocardium, so the electrocardiogram machine plays an important role in the examination of heart disease. [0003] Existing electrocardiogram machine is divided into single-channel electrocardiogram machine and multi-channel electrocardiogram machine according to recorder output channel number, and mainst...

Problems solved by technology

When the waveform is drawn, crossover and blank coexist, and the drawing effect is not beautiful

[0006] 2)) The waveform voltage amplitude distribution of each channel is uneven. It is judged that the waveforms of adjacent channels crossover, and the waveform gain is reduced, which will make the waveform amplitude of the voltage amplitude smaller, which will affect the doctor's diagnosis.

[0007] 3) The waveform voltage amplitude of some patients is too large, and the waveform will still appear out of bounds and crossover when the gain is reduced

Further reducing the waveform gain will have too much influence on the doctor's diagnosis

[0008] Evenly distributing the baseline position of the waveform in the drawing area will cause the ECG waveform to cross the border and cross, and will also cause a waste of drawing space. Crossover, but there are still some defects and deficiencies
