Three-Lead Electrocardiograph with Display and Printing System

Abstract:

This document is the product of the work developed during 18 months framed in the line of research of the university, oriented to production and society. The motivation of the research team was to develop a prototype of an electrocardiograph of three derivations of bio-potential signals, which is a graphic representation of the bioelectric activity of the cells that make up the heart muscle. Allowing specialists in the area to evaluate the state of conduction of this organ and the appearance of pathologies caused by damage to the conduction tissues of the electrical signals of the heart safely, through a portable, compact equipment with visualization of these signals and wireless communication for remote visualization, between different mobile devices with Android operating system. This paper will indicate the design stages for signal acquisition, amplification, filtering, digitalization of the same and DC-DC power supply that will give the necessary autonomy to the equipment and communication for operation in any environment and low cost. In such sense the objectives planted in this investigation were achieved, with the development of an equipment with high operational performance, excellent electronic design in all its phases of design and conditioning, filtering, amplification and digitalization of the bio-potential signals and wireless communication between mobile devices.
