Diseño y construcción de un sistema para asistencia en la realización de la prueba de esfuerzo o ergonometría

Abstract

The present project includes the design and construction of a prototype for assistance in the stress test, which consists of two elements: a bracelet and a portable ECG, which are responsible for the measurement of two types of variables: environmental (environmental temperature, atmospheric pressure, relative humidity, ambient light). And bio-signals (oxygen saturation, heart rate, body temperature, blood pressure and three electrocardiogram leads that are V2, V5 and II). The acquired data from the patient prior to the test to determine if it is suitable for the continuation of the test, as well as to analyze if the environmental conditions of the room are in accordance with the standards of the same. While the ECG signals are analyzed with the patient in motion until reaching the theoretical maximum heart rate. The data in both cases acquired and transmitted between the equipment with bluetooth connectivity and the user interface through XBEE transmitters. All the calculation algorithms are part of the equipment and the interface only used for an adequate presentation; it is also available of the storage of the data in removable memories in case of use of the equipment in the form of Holter.
