Research On Cardiopathy Detection Based On Embedded Computer System

Cardiovascular disease has long been the major diseases threatening human life. Human remains one of the main causes of death, heart disease is the number one killer of human health. One-third of the world's population died of heart disease is caused by our country, every year, tens of thousands of people died of a heart attack. Heart disease in the United States and Japan, the European population, is the first disease mortality, which ranks third in China. However, in recent years it is rising soon. In the heart of the detection instruments, ECG and heart sounds are the most common diagnostic methods. ECG and heart sound signals contain a lot of information on the state of the heart.In this paper, under the analysis of the study abroad on the basis of the status quo, using embedded system platform, we developed a Wireless Remote ECG Monitoring System and an Embedded Heart Sound Analyzer, the integrated use of the embedded microprocessor technology RF wireless technology, embedded TCP network technology, USB technology, and so on. The equipment has been developed into a clinical trial, the clinical results achieved to a certain extent.The main works in this paper are listed as follows:㈠Completion of the "Long-range Wireless Network ECG Monitoring System".①Explore the development of "long-range wireless network ECG monitoring system" program.②Designing a portable ECG data acquisition system, including ECG amplifier, ADC, and wireless data transceiver.③Created an embedded wireless ECG network transponder.④Completion of the "long-range wireless network ECG monitoring system" clinical trial.㈡Complete the "Embedded Heart Sound Analysis".①ECG and heart sounds collection suitable for analog circuits, digital circuits, and signal processing methods, for audio sampling intervals to live up to the simulation.②Explore USB data communication applications in the heart sounds.③Results Using LabVIEW software development platform for users of the application, the following functions : collecting, and the preservation of the heart sound signals broadcast; patient management information and data; Music and Audio intervals database showed heart; and the murmur of the heart sounds for energy, and time-frequency analysis. Access to the features of heart sound signals; R-wave intentions -- the heart of a threshold calibration to achieve accurate positioning.④Clinical data collection and analysis.
