Abstract：To provide reference for the troubleshooting of ECG-1350C multichannel electrocardiograph, the equipment principle and
clinical application functions were described in detail, and three typical practical maintenance cases were used for troubleshooting. The
paper-feeding motor of the multi-channel electrocardiograph was improved according to the observation method, replacement method,
meanwhile, the test method and SD wireless LAN card, and the USB interface slot were repaired and improved. By fully understanding
of the principle of multichannel electrocardiograph and the use of various clinical application functions, the fault caused by the paper
motor, SD wireless LAN card, and USB interface slot was repaired. The repair of the three faults was summarized and analyzed. Based
on this, improving the design defects of the device can save maintenance costs and reduce the subsequent failure rate of the device.
