Abstract

CLASSIFICAçãO MULTIPARAMéTRICA DE SOM CARDIOVASCULAR. A presente invenção refere-se a um método para classificar um som cardiovascular gravado a partir de um paciente com vida. O método compreende as etapas de: identificar segmentos de diástole e/ou de sístole do som cardiovascular; dividir pelo menos um dos segmentos de diástole e/ou de sístole identificados em um número de subsegmentos compreendendo pelo menos um primeiro subsegmento e pelo menos um segundo subsegmento; extrair do primeiro subsegmento pelo menos um primeiro parâmetro de sinal caracterizando uma primeira propriedade do som cardiovascular, extrair do segundo subsegmento pelo menos um segundo parâmetro de sinal caracterizando uma segunda propriedade do som cardiovascular; classificar o som cardiovascular usando pelo menos o primeiro parâmetro de sinal e pelo menos o segundo parâmetro de sinal em um método de classificação de multivariáveis. Além disso, a invenção refere-se a um sistema, estetoscópio e servidor para classificar um som cardiovascular gravado a partir de um paciente com vida, em que o método acima descrito foi implementado.
