DISEÑO Y CONSTRUCCIÓN DE UN FONOCARDIÓGRAFO DIGITAL CON VISUALIZACIÓN EN LABVIEW
Resumen
Un buen diagnóstico de enfermedades relacionadas con válvulas cardiacas se debería dar a partir de un fonocardiograma capaz de suministrarle al médico una información confiable de la situación del paciente. Se presenta el diseño de un fonocardiógrafo con la capacidad de amplificar y filtrar las señales acústicas derivadas del corazón. Posteriormente se realiza una conversión análogo-digital de las señales para ser enviadas por puerto serial a un entorno gráfico en LabVIEW para su registro y análisis en tiempo real.
Abstract—The auscultation of the heart noises has always been an important tool in medicine, a good diagnosis of illnesses related to the heart valves should be given from a phonocardiogram able to give the doctor a reliable information of the patients situation. The design presented is a phonocardiograph capable of amplifying and filtering the acoustic signs derived from the heart. After an analog to digital conversion of those signs the information is sent by serial port to a graphic environment in LabVIEW for its registration and analysis in real time.
