Problems solved by technology
Low-end ECG machines and higher-end ECG machines have the advantages of low price, small size, and portability, but they also have the disadvantages of small output channels and inconvenient comparison and observation by doctors.
Therefore, the present invention proposes an upwardly compatible method, which solves the shortcomings of the traditional low-end electrocardiogram machine, which has a small number of output channels and is not convenient for doctors to compare and observe.

Embodiment Construction
[0009] figure 1 It is the traditional output mode of the three-channel ECG machine, each column outputs 3 waveforms, and the twelve ECG waveforms are divided into 4 columns for output. figure 2 Then use the method of the present invention to output twelve ECG waveforms on the printing paper of the three ECG machine. It changes the horizontal direction of the printing paper from time output to voltage amplitude output, and the vertical direction from voltage amplitude output to time output. so figure 2 On the printing paper of the three-channel electrocardiograph, twelve waveforms are output in a single column, that is, the three-channel electrocardiogram is compatible with the twelve-channel electrocardiogram.
[0010] image 3 It is the traditional output mode of the six-channel ECG machine, each column outputs 6-channel waveforms, and the twelve-channel ECG waveforms are divided into 2 columns for output. Figure 4 Then use the method of the present invention to output...

The invention relates to a method for realizing upward compatibility of the types of electrocardiographs, in particular to a method for realizing compatibility between a single channel electrocardiograph and three-channel, six-channel and twelve-channel electrocardiographs, compatibility between the three-channel electrocardiograph and the six-channel and twelve-channel electrocardiographs and compatibility between the six-channel electrocardiograph and the twelve-channel electrocardiograph, i.e. the method can realize outputting three-channel, six-channel and twelve-channel electrocardiogram wave forms in the conventional single channel electrocardiograph in a single row, realize outputting the six-channel and twelve-channel electrocardiogram wave forms in the conventional three-channel electrocardiograph in a single row, realize outputting the twelve-channel electrocardiogram wave form in the conventional six-channel electrocardiograph in a single row and realize outputting multi-channel electrocardiogram wave forms in the conventional twelve-channel electrocardiograph. Theoretically as long as the printing paper is long enough, the amount of the wave forms output in a single row can be increased infinitely.
Description
technical field [0001] The invention relates to a method for realizing upward compatibility of electrocardiograph machines. More specifically, single-channel electrocardiographs are compatible with three-, six- and twelve-channel electrocardiographs, three-channel electrocardiographs are compatible with six- and twelve-channel electrocardiographs, and six-channel electrocardiographs are compatible with twelve-channel electrocardiographs. That is to say, it is possible to output three, six and twelve ECG waveforms in a single row in a traditional single-channel ECG machine, and to realize a single-row output of six and twelve ECG waveforms in a traditional three-channel ECG machine. In the six-channel electrocardiograph, the twelve-channel ECG waveform can be output in a single column. In the traditional 12-channel ECG machine, more ECG waveforms can be output. Theoretically, as long as the printing paper is long enough, the number of single-column output waveforms can be infi...
