Abstract
In this study, Discrete Wavelet Transform(DWT), which can detect more correct QRS complex, approximated through impulse response for reducing complexity to suit real-time system during exercise. Also, rhythm information, which is Arrythmia, Bradycardia and Tachycardia, is provided through continuously monitoring QRS complex. Proposed algorithm is evaluated by computer simulation of ECG signal that is measured during exercise.
본 논문에서는 운동 중 실시간 구현을 위해 정확한 QRS 검출이 가능한 이산 웨이블릿 연산을 임펄스 응답으로 근사화 하여 연산량을 줄였다. 또한, 지속적인 QRS 검출로부터 부정맥, 빈맥 그리고 서맥등의 정보를 제공한다. 제안 알고리듬은 운동 중 수집된 생체신호를 컴퓨터 시뮬레이션을 통해 평가한다.
