Abstract

An ECG(Electrocardiogram) compression can increase the processing speed of system as well as reduce amount of signal transmission and data storage of long-term records. Whereas conventional performance evaluations of loss or lossless compression algorithms measure PRD(Percent RMS Difference) and CR(Compression Ratio) in the viewpoint of engineers, this paper focused on the performance evaluations of compression algorithms in the viewpoint of diagnostician who diagnosis ECG. Generally, for not effecting the diagnosis in the ECG compression, the position, length, amplitude and waveform of the restored signal of PQRST wave should not be damaged. AZTEC, a typical ECG compression algorithm, is validated its effectiveness in conventional performance evaluation. In this paper, we propose novel performance evaluation of AZTEC in the viewpoint of diagnostician.

심전도의 압축은 시스템의 처리 속도를 높일 뿐만 아니라 신호의 전송량, 장기적인 기록 데이터 저장량을 줄일 수 있다. 본 논문에서는 기존의 심전도 데이터의 손실 혹은 무 손실 압축 알고리즘에 대한 성능 평가가 엔지니어의 관점에서 PRD(Percent RMS Difference)와 CR(Compression Ratio)을 측정하였다면 심전도를 진단하는 진단자의 관점에서 압축의 성능 평가에 대한 연구를 하였다. 일반적으로 심전도 데이터의 압축이 진단에 영향을 미치지 않게 하기위해서는 압축 후 복원된 PQRST파의 위치, 길이, 진폭, 파의 형태 등 진단에 필요한 것들이 손상되어선 안 된다. 대표적인 심전도 압축 알고리즘 AZTEC은 기존의 성능평가에 그 효율성이 검증되었지만 진단자의 관점에서 새로운 성능평가를 제시한다.
