Abstract

Physical and psychological problems, and economic costs generated by Cardiovascular Diseases are affecting an important number of people around the world, and mainly in developing countries. Access to early detection and treatment is not common because of the scarcity of specialists and equipment, especially in rural areas. In order to address this problematic, an inexpensive portable Electrocardiograph device with Smartphone connectivity is proposed in this document. Firstly, an electronic circuit will be in charge of amplifying, filtering and sampling the Electrocardiogram (ECG) signal of a subject acquired by means of the use of Ag/AgCl electrodes. Then, the sampled data is transferred to an Android based system in order to be processed, displayed and analyzed on the application. Finally, the ECG time series can be printed or stored into a file which can be sent to a cardiologist. The resulting device is a less costly and easier to access gadget, which also provides a reliable signal resolution for a primary analysis of different diseases.
