The Implementation of ECG Monitoring Medical System based on Mobile Platform

With the development of smart phones and mobile terminals, mobile health would play an important role in the treatment of heart disease. This paper presents an ECG monitoring medical System based on mobile platform. This system Consists of Data Collection Terminal, ECG Monitoring Terminal, Health Records Management Platform,Mobile Terminal. ECG data is collected by Data Collection Terminal. Eventually, ECG data will be sent to the platform via Bluetooth and other communication technology. The doctor could feedback the diagnose to the user’s mobile Terminal. Our main target is to provide timely and reliability services to patients and reduce cost and increase efficiency in home health-care, community health-care.


Introduction
Mobile computing platforms are going to dominate the information communication technology (ICT)sector in this age of rapid technological innovations.1 Especially,smart phones were more and more popular than personal computer in recent several years.Mobile terminals are already being used for public health program. Nowadays, cardiovascular diseases(CVD) are known to be the most widespread causes to death. 2 The electrocardiography (ECG) which is a sign of biological signal is an electrical activity of the heart as detected by electrodes attached to the surface of the skin.3 ECG is used by doctors to treat heart disease. In recent years, the research of mobile ECG Monitoring Medical System has very broad application prospects. The system can provide timely services to patient anywhere they want. With the widespread popularity and application of smart phone, Intelligent mobile phone would play a key role in ECG Monitoring Medical System.
In this paper, ECG Monitoring Medical System based on mobile platform is proposed. This article focuses on the ECG Monitoring Medical System's architecture and four modules: Perception Module, Transport Module, Service Module, Application Module and its application.

3.1Perception Module
Data Collection Terminal generated signals through ECG cable. The AD converter can convert signals into digital signals. The monitoring terminal is designed by using MPS430 in the other paper, which is (4) and(5).  A number of emerging medical application ECG require DSP(Digital Signal Processing) processing performance at very low power. The TMS320C5515 digital signal processor is ideally suited for such applications. A typical medical application includes: Signal processing algorithms for signal conditioning,performing measurements and running analytics on measurement to determine the health condition.
User control and interaction, including graphical display of the signal processing results and connectivity to enable remote patient monitoring.
The TMS320C5515 digital signal processor is also responsible for managing user control and interaction including graphical display of the signal processing results.

3.3Service module
The Health Records Management Platform is responsible for receiving the ECG data from ECG Monitoring Terminal. The ECG data is sent via Wifi, GPRS, 3G and 4G to database for storage and later reference. A web application allows accessing data from any device with internet connectivity.
In order to cope with the pressure of data processing, the data processing technology has a lot of innovation and development in the past ten years. Data warehouse is also very important in this system. The new situation has put forward a series of new requirements to the database, and needs to have high efficiency and fast data storage and analysis ability, big data compression ability, high performance to price ratio and so on. MPP (Massively Parallel Processing) database provides a highly efficient, low-cost solution. Using distributed computing architecture, data parallel processing on multiple independent nodes, which greatly improves the speed of operation. This distributed storage technology for data storage can reduce the cost of data processing and ensure service quality.

3.4Application Module
In this module, we show our implementation of ECG Monitoring Medical System based on mobile platform.
As shown in Fig4&5, we chose 12 lead ECG output using 10 electrode input and the phone we use is an android OS. User could see some diagnosis results from the phone's screen. A remote detailed diagnosis could be done if the wireless connection between the mobile phone and Health Records Management Platform is available. In addition, Users can also build their own records by uploading and saving the diagnosis results in management platform. What's more, we also calculate and show the heart rate.After tests, the system proves itsreliability, stability and conveniently. Fig6 Shows the testing environment and results.

Conclusion
In this paper, ECG Monitoring Medical System based on mobile platform is proposed. The system can collect ECG data in Data Collection Terminal and save those data in ECG Monitoring Terminal.Meanwhile, it provides accurate and reliable basis for attending doctors to carry out follow-up diagnosis. ECG Monitoring Medical System provides convenient, fast and sustainable solutions for health resource management of individuals and the whole society. User can effectively receive professional medical diagnosis and treatment recommendations anywhere and anytime. The performance after the application of detailed testing and analysis,proved that ECG Monitoring Medical System is user-friendly, low-cost, stability and reliability.
