| Abstract |
Since a long time, most of the research and development of medical electronic equipment focused on the hardware circuit design, the physiological signal acquisition and data transmission, few of the analysis and determine the abnormal condition. In this context, this paper proposed a windowing interface ECG measurement system; this system has to determine the function of sinus rhythm abnormalities, including ECG instrument hardware development, and writing software programs to determine abnormal heart rhythm. Unlike conventional 12-lead method, the system uses the hand holding the metal ball and the foot with metal plates to retrieve the ECG, is a 1-lead method. In determine the function of the abnormal heart rhythm, taking sinus P wave and R wave to analyze, and write a software program for heart rhythm abnormalities judgments. In the man-machine interface development, this system uses LabVIEW software as the windows user interface development tools, the interface design were also considering the needs of patients and medical staffs have different functions displayed. In order to make research with practical features, we have normal and abnormal heart rate tests respectively to verify system performance. Experimental results show, this research has the accuracy, easy to use, easy portability and low cost advantages. It not only can be applied to health care institutions or home care, can also provide medical and care staff as a basis for subsequent processing. |
