Device and method for collecting 18 lead electrocardio signals

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.
