Resumo
O conceito de saúde indica que por um lado um indíviduo ou grupo é capaz de realizar as suas aspirações e satisfazer as suas necessidades e por outro lado modificar ou lidar com o meio que o envolve sendo assim uma dimensão de qualidade de vida e não o objetivo de vida. Os alunos que ingressam pela primeira vez no ensino superior devido a vários condicionantes sofrem de stress psicológico. Uma aproximação ao estudo do impacto do stress sentido pelos alunos passa pela análise de dados biológicos em diferentes períodos num evento de stress como uma apresentação oral. Foram recolhidos sinais de ECG dos alunos do primeiro ano do curso de Engenharia biomédica da Universidade de Trás-os-Montes e Alto Douro numa apresentação oral e estudadas as séries de intervalos de tempo adquiridas através de metodologias lineares e não lineares

Students who first enter in higher education, due to various conditions suffer from psychological stress. An approach to the study of the impact of stress felt by students involves the analysis of biological data in different periods in a stress event as an oral presentation. ECG signals from the first year students of the Biomedical Engineering course at the University of Tr´as-os-Montes and Alto Douro were collected in an oral presentation and the acquired time series studied were studied using linear and non linear metodologies.
