| Abstract: | This paper introduces the hardware and software of the measuring system of the ventricular late potential. The system consists of low noise, high gain and CMRR acquiring circuit and microcomputer. The signal processing program is a main characteristic of the measurement system. It has contained QRS test and then signal-averaged process of the cardiac electric signal. The results with the high resolution, showing the characteristic values contained in the signal-averaged electrocardiogram, have been displayed or printed out in the end. |
