Description

technical field [0001] The invention relates to a computer-controlled electrocardiograph, in particular to a computer-controlled common-mode voltage negative feedback electrocardiograph, which belongs to the technical field of computer intelligent control. Background technique [0002] The traditional ECG machine must include a recorder for ECG display. The recorder is a device that converts the current change of the ECG signal into a mechanical (stylus pen) movement. The shaft on the recorder is offset with the change of the ECG signal. The recording pen on the rotating shaft also shifts accordingly, and the magnitude of the deviation represents the voltage amplitude of the ECG signal. At the same time, the recording paper under the recording pen is rolled, and the recording pen will draw an electrocardiogram on the recording paper; the electrocardiogram used in hospitals now The ECG machines are basically traditional ECG machines instead of ECG machines made with virtual i...

[0002] The traditional ECG machine must include a recorder for ECG display. The recorder is a device that converts the current change of the ECG signal into a mechanical (stylus pen) movement. The shaft on the recorder is offset with the change of the ECG signal. The recording pen on the rotating shaft also shifts accordingly, and the magnitude of the deviation represents the voltage amplitude of the ECG signal. At the same time, the recording paper under the recording pen is rolled, and the recording pen will draw an electrocardiogram on the recording paper; the electrocardiogram used in hospitals now The ECG machines are basically traditional ECG machines instead of ECG machines made with virtual instrument technology. Although some manufacturers have launched ECG machines based on virtual instrument technology, there are still very few such manufacturers, and traditional ECG machines use paper The working method of recording the electrocardiogram requires the electrocardiograph to use analog circuits to process the signals. Its structure includes a large number of analog circuits, a recorder related to mechanical movement, and a paper-feeding transmission mechanism that controls paper-feeding, etc., which is very complicated. It is also difficult to draw a 12-lead ECG at the same time. In addition, the ECG is drawn on paper, which is easy to lose and difficult to archive for a long time; and the existing ECG machines cannot communicate with the network and cannot share resources
