Abstract(s)
As doenças cardiovasculares são a principal causa de morte na Europa e em Portugal. A prática de auscultação dos sons emitidos pelo coração ´e de grande importância para identificação de doenças cardíacas e em caso de mau funcionamento permite estabelecer estratégias iniciais de combate à doença. Este projeto teve como finalidade desenvolver um sistema que adquire e regista os batimentos cardíacos em tempo real de forma de identificar anomalias cardíacas. O projeto desenvolvido é uma aplicação multiplataforma capaz de funcionar com conexão a um dispositivo externo do PCG para captura dos sinais emitidos pelo coração ou pode adquirir os sinais através da aplicação com auxílio de um microfone. O sinal recebido através do microfone ´e condicionado, através de filtros digitais de forma a obter o sinal com a melhor qualidade possível para análise do paciente. A aplicação representa graficamente o sinal sonoro capturado e a sua Fast Fourier Transform. Os sons capturados podem ser exportados sob forma de um ficheiro .wav para uma análise sonora do sinal.

This project aimed to develop a system that acquires and records heartbeats in real time in order to identify cardiac anomalies. The developed project is a multiplatform application capable of working with connection to an external device of the PCG to capture the signals emitted by the heart or it can acquire the signals through the application with the assistance of a microphone. The signal received through the microphone is conditioned, through digital filters in order to obtain the signal with the best quality possible for analysis of the patient. The application graphically represents the captured sound signal and its Fast Fourier Transform. The captured sounds can be exported in the form of a .wav file for a sound analysis of the signal.
