Abstract

SISTEMA PARA GERAR SINAIS DE SAÍDA INDICATIVOS DA QUALIDADE DE CONTATO E METODO PARA DETERMINAR QUALIDADE DE CONTATO DE DIVERSOS ELETRODOS ACOPLADOS A UM PACIENTE São providos um sistema e método para gerar sinais de saída indicativos da qualidade de contato de diversos eletrodos acoplados em um paciente. Um gerador de sinal acoplado a um eletrodo de referência injeta um sinal alternado no paciente. Diversos atnplificadores diferenciais, cada um acoplado a um respectivo dos diversos eletrodos para detectar um sinal de entrada a partir do paciente, são operáveis para emitir um respectivo sinal de saída em resposta a um respectivo sinal de entrada. O sinal de saída gerado pelo respectivo amplificador diferencial é indicativo da qualidade de contato para o respectivo eletrodo.
