12 W elcome Message from Rector of Universidad Politécnica Salesiana Investigation and innovation constitute essential functions of higher education institutions. It is starting from scientific research, as a systematic and methodic reflection process, that knowledge is promoted in order to develop the good living concept. This idea has moved Universidad Politécnica Salesiana to host Andescon 2012, since this event provides an extraordinary opportunity to encourage youngsters to contribute actively from their field of study, focused to the new knowledge and technology which in the short and long run will contribute to the progress of this country. Educating university students implies on one hand, the formation of individuals who are capable to be critical thinkers in front of the reality by looking at it, analyzing it and exploring it. On the other hand, it is the formation of honest and ethical citizens at their total capacity of action, including their research work. The Universidad Politécnica Salesiana, among others, constructs its basis in a place where its young university students are the subjects of their own development as honest citizens and good Christians, with professional and moral proficiency to act towards their own society s benefit. To address the social context, in its real global dimension, the university system is forced to characterize the different phenomena by assuming a political, social, intellectual and academic position which supports and feeds back the research processes with the focus of achieving the GOOD LIVING. We are witnesses of how science and technology are set under the market s service, with the evident criteria of efficiency, profitability and functionality, and during this process, a new culture of indiscriminate usage of natural resources is created. This business commodification of knowledge produces the crisis of inequity and impoverishment affecting great social collectives. Therefore, becoming actors who recover science and technology in order to meet the needs of societies without predating the environment and respecting the nature s order, implies constructing conditions for the good living. Our world requires more men and women who add up efforts and share knowledge and know how to make of science and technology public areas. Some progress has been made in this direction in Internet, similar processes could occur with biotechnology, microelectronics, industrial production, data flows and other fields. This battalion of men and women, some academic and researcher, others students, are capable of creating appropriate conditions for that OTHER POSSIBLE WORLD built on the basis of values such as solidarity, equity, sustainability, participation and respect to the life and the environment. xii

23 2012 Andean Region International Conference ECG Signal Monitoring using Networked Mobile Devices Enrique V. Carrera Department of Electrical Engineering Ecuadorian Armed Forces University P. O. Box B, Sangolqui, Ecuador Pamela Morales Systems Engineering Department University San Francisco of Quito P. O. Box , Quito, Ecuador Abstract Aging populations and increasing rates of chronic diseases are overwhelming even the most efficient health care systems. Technology has the potential to move health care to a more proactive, consumer-centric model of care, capable of improving cost, quality, and accessibility of health care services. However, there are still many problems to solve before having fully functional, reliable, secure and efficient remote health care systems. Thus, this paper presents a working implementation of a system for monitoring health conditions using sensor networks and wireless communication technologies. Although, our prototype is focused on the monitoring of electrocardiogram signals, the proposal comprises an experimental platform to analyze several factors contributing to the reliability, safety and efficiency of remote health care structures. In addition, our proposal will be the starting point for implementing networked portable devices oriented to the continuous monitoring of elderly or chronically ill patients. Keywords-Sensor networks, mobile computing, remote health care, electrocardiogram monitoring. I. INTRODUCTION The global population is getting older. The worldwide population over age 65 is expected to more than double from 357 million in 1990 to 761 million by 2025 [1]. Thus, the length of time that people live with chronic diseases such as heart disease, cancer, Alzheimer s, and other forms of dementia, is increasing. This circumstance places enormous demands on health care systems, not solely in terms of acute hospital care but also for routine monitoring and health maintenance on a massive scale. Providently, substantial efforts are being made to deploy IT (Information Technology) and other technologies into the clinical environment, particularly the hospital arena. Moreover, deployment of technology in support of at-home care has the potential to radically reduce the pressure on hospital resources. At-home care can potentially provide many advantages in terms of financial benefits, improved quality of life for patients, and more effective detection or monitoring of many long-term chronic diseases [2]. Consequently, medical devices, IT and communications have started to converge in order to revolutionize health care in the home. Also, advances in technology will make it possible for people to play a greater role in maintaining and monitoring their own health [3]. Important proposals in this direction have suggested the use of wireless sensor networks (WSNs) for implementing health care in the home [4]. WSNs can easily be coupled to several wireless communication technologies (e.g., Bluetooth, WiFi), resulting in extremely flexible systems with minimal impact on the lives and surrounding environment of the patients. However, there are still many problems to solve before having fully functional, reliable, secure and efficient remote health care systems. In fact, the potential value of WSNs in the health care field has not yet been fully exploited [5]. Significant research efforts are still required to determine, for instance, the most adequate WSN architecture for monitoring health conditions, the most reliable and secure communication technology for remote health care, the type of analysis that can be performed on the large amount of health-related data in order to support physician decision making. Based on that, this paper presents a working implementation of a system for monitoring health conditions. In particular, our prototype is focused on the remote monitoring of electrocardiogram (ECG) signals. The system design depends mainly on mobile devices, Web services and wireless communication technologies. Specifically, a smartphone receives a digital ECG signal using Bluetooth, processes the signal, and sends critical information to a server. The communication between the smarthphone and the server can be based on different communication technologies, according to its requirements. In addition, the server keeps the data and allows their visualization to physicians and patients. If some problems are detected, alert messages are also sent to the patient and its corresponding physician. The implemented system evolved into an experimental platform that allows to analyze several factors contributing to the reliability, safety and efficiency of a remote health care system. This prototype will also be the starting point for implementing networked portable devices oriented to the continuous monitoring of physiological and physical conditions (e.g., heartbeat rate, blood pressure and flow, temperature, oxygen saturation, physical activity, and even location). We hope that in the near future, systems like our prototype allow to adequately attend elderly or chronically ill patients, /12 $ IEEE DOI /Andescon
