Problems solved by technology
However, the ECG signals obtained in this way are time-sharing samples, and the doctor needs to re-place the electrodes before the second sampling, which will take a certain amount of time. It is estimated that the time interval between the two samplings will reach more than 5S, and the two sampling The obtained 18-lead ECG signal is not a synchronous ECG signal
Because there is a certain time difference between the two samplings before and after, doctors cannot correspond the waveforms of the two samplings in time. great inconvenience

The invention relates to the technical field of electrocardiographs, and particularly relates to a device and a method for collecting 18 lead electrocardio signals. The method comprises the processes as follows: 15 paths of lead signals are respectively obtained from a human body signal through 15 lead signal collection channels and a reference signal collection channel; the lead signal collection channels are connected with a gain amplifying unit, and are used for carrying out processing and gain amplification on all lead signals, so as to obtain 14 paths of electrocardio signals; the gain amplifying unit is connected with an analog-to-digital conversion unit; the analog-to-digital conversion unit is used for converting the 14 paths of electrocardio signals to obtain 14 paths of electrocardio digital signals; the analog-to-digital conversion unit is connected with an electrocardio signal processing unit; the electrocardio signal processing unit is used for calculating the 14 paths of electrocardio signals, so as to obtain the 18 lead electrocardio signals. According to the device and the method, synchronous collection of the 18 lead electrocardio signals is achieved; the problem that 18 lead electrocardio waveforms cannot be synchronously collected by the prior art is overcome; the signal collection accuracy is improved.
Description
technical field [0001] The invention relates to the technical field of electrocardiographs, in particular to an eighteen-lead electrocardiographic signal acquisition device and method thereof. Background technique [0002] The electrocardiogram machine is a kind of conventional diagnostic medical equipment for electrocardiographic examination. The existing electrocardiogram machines generally include single-channel, three-channel, six-channel and twelve-channel electrocardiogram machines according to the number of output channels of the recorder; The electrocardiograph is the most advanced one in the existing technology. It generally includes twelve lead data, which are: limb I lead, limb II lead, limb III lead, pressurized AVR lead, pressurized lead The AVL lead, the pressurized AVF lead, and the ECG signals of the chest leads V1-V6 provide necessary diagnostic information for clinicians. Usually, the conventional twelve-lead data can already meet the clinical needs for th...
