Abstract

"MéTODO E SISTEMA DE DETECçãO EGC DIGITAL". Um sistema de detecção de onda R inclui um eletrodo (12) para colocação em vizinhança próxima a ou em contato com um coração para detectar atividade elétrica do coração. Um processador de sinais (16) está em comunicação com o eletrodo, e é responsivo à recepção do sinal análogo a partir do eletrodo para condicionar o sinal para considerar ruído, e efeitos de campo distante. O sistema é operativo para determinar se o sinal condicionado excede um valor limite dinâmico, e, se exceder, o sistema gera um pulso de sincronização para indicar a borda surgindo de uma onda R.
