An electrocardiogram signal diagnostic parameter extraction device, wherein the electrocardiogram signal diagnostic parameter extraction device has an electrocardiogram signal input unit that receives an electrocardiogram signal including a plurality of sample data, a plurality of storage spaces, and is input over time. A peak for detecting peak sample data among the plurality of sample data by comparing at least two or more of the plurality of sample data, a first buffer in which each of the sample data is sequentially stored in each of the plurality of storage spaces of the first buffer The detection unit, the current sample data which is the peak sample data, and each of the L1 previous sample data from the first previous sample data of the current sample data to the first L1 th previous sample data of the current sample data are part of the second buffer Stored in a storage space (where L1 is a natural number), each of L2 subsequent sample data from the first and subsequent sample data of the current sample data to the L2 and subsequent sample data of the current sample data is stored in the second buffer The average value between the values stored in the second buffer, the values stored in the second buffer, and the values previously stored in the third buffer, which are stored in some other storage space (where L2 is a natural number), is newly stored in the storage space of the third buffer. A diagnostic parameter extraction unit extracting a diagnostic parameter of the electrocardiogram signal using at least one of values stored in the third buffer and the second buffer, values pre-stored in the third buffer, or values newly stored in the third buffer It can contain.심전도 신호 진단 파라미터 추출 디바이스에 관한 것이며, 심전도 신호 진단 파라미터 추출 디바이스는 복수의 샘플 데이터들을 포함하는 심전도 신호를 입력받는 심전도 신호 입력부, 복수의 저장 공간을 갖되, 시간의 흐름에 따라 입력되는 상기 복수의 샘플 데이터들 각각이 제 1 버퍼의 복수 저장공간 각각에 순차적으로 저장되는 제 1 버퍼, 상기 복수의 샘플 데이터들 중 적어도 둘 이상을 상호 비교하여 상기 복수의 샘플 데이터들 중 피크 샘플 데이터를 검출하는 피크 검출부, 상기 피크 샘플 데이터인 현재 샘플 데이터와, 상기 현재 샘
