One of the most important organs in the human body-the heart, unlike some parts outside the body, can be found immediately after problems occur and solved quickly. So, when there is something wrong with the heart, how to do the test? Everyone has heard of the commonly used detection tool ECG monitor. EEG machine  Monitor manufacturer How does it work?


I. Working methods


From a broad perspective, the ECG module obtains weak ECG signals from human body through lead wires, and after input buffering, digital resistance network signal weighting and lead definition, pre-amplification, high-pass filtering, analog-to-digital conversion, etc., the interference is removed by digital filtering algorithm. The ECG module uses 4000V isolated floating power and photoelectric isolation separately, and then the ECG signal is transmitted to the microcomputer by the communication adaptation circuit. The working state of ECG module is controlled by microcomputer through data command. After acquiring ECG data from ECG module, the microcomputer completes a series of work such as ECG display, storage, printing, data management, waveform parameter calculation and analysis, patient data management, etc.


II. Characteristics


The main characteristics of ECG monitor are that it has nine ECG analysis functions, covering the nine common ECG analysis functions at present; It is easy to make a clear and accurate electrocardiogram with sampling function; The humanized design of ECG report can make users get the report quickly; Make the ECG baseline return to the reset function quickly, avoid waiting for a long time, and get what you see is the analysis window; Observe the results directly on the preview report, practical "comparison" function; Two reports can be called up for comparison at the same time, and the diagnosis report can be input quickly; Improve the function of diagnosis template, write diagnosis quickly, and fully open knowledge base function; You can quickly inquire and edit the knowledge of concerned electricity.


III. Dynamic electrocardiogram


Dynamic electrocardiogram (DCG) can continuously record and count the changes of human heart in active and quiet state for 7*24 hours, and present the relevant data in the form of examination report. The detection rate of arrhythmia is higher than that of routine examination, and the hidden dangers of heart health can be found in time. (1) statistical records of the frequency and time of abnormal ECG in 24 hours; ② Intercept ECG waveform when abnormality occurs; ③ Playback the recorded real-time electrocardiogram.


The monitor manufacturer pointed out that, from this point of view, the ECG monitor needs to be worried about when it is used, but its function is really powerful, which can help the elderly, pregnant women and other needy people to detect in time, otherwise, the heart diseases will not be visible.
