| Summary: | 碩士 === 東南科技大學 === 電機工程研究所 === 101 === The main function of the heart is to pump blood to various parts of the body; it is one of the key components with human organs to maintain normal operation. Electrocardiogram (ECG) recording is a reference to investigate the heart is normal or not. Most conventional electrocardiographs are bulky; it shall be operated by health care professionals and explained by a doctor. ECG machine for home use is getting more popular recently; however most of those machines presented waveform and beat frequency and few of the analysis and determine the abnormal condition. Therefore, this paper attempts to create a precise, lightweight, easy to operate and full-featured ECG measurement system.
The main purpose of this paper is development an ECG measurement system with remote synchronization control and analysis of abnormal heart rhythm, 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. In addition, considering the future telemedicine care, the system combined with remote WEB function. 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.
