Multifunctional electrocardiograph detecting instrument

The utility model belongs to the field of instruments, especially an electrocardiograph detecting instrument. The multifunctional electrocardiograph detecting instrument comprises a control circuit and the control circuit consists of a host computer control module, a detecting signal generation module and lead connection interfaces. The keyboard, the liquid crystal display (LCD), the touch screen, the SRAM and the flash module of the host computer control module are respectively connected with the CPU module of the host computer control module. The common mode rejection ratio detecting module, the DAC circuit and the channel selection circuit of the detecting signal generation module are respectively connected with the MCU of the detecting signal generation module. The host computer control module and the detecting signal generation module are connected with each other through an RS-232 interface circuit. The MCU of the detecting signal generation module is directly connected with the lead connection interfac
