Abstract
The body surface ECG(electrocardiogram) is produced by the electric fields caused by the propagation of action potentials within the myocardial cells. The repolarization phase of the action potential is very sensitive to factors of clinical importance. Therefore, in this paper of the inverse electrocardiography, we studied a method of estimating the uniform action potentials during repolarization phase from the body surface ECG using digital signal identification techniques. The estimated action potential of a normal was similar to that of clinical data in the repolarization phase.
심전도는 심장근육세포와 홍분세포들의 활동전위의 전파에 따른 전파에 의해 발생한다. 활동전위의 재분극상은 임상적 요인에 매우 민감하다. 따라서. 역심전도에 관한 본 논문에서는, 디지탈 신호 추정방법으로 심전도의 재분극상에서의 일정활동전위(uniform action potential)를 추정하는 방법을 연구하였다. 추정된 정상인의 활동전위는 임상적 자료와 비슷한 재분극상을 보였다.
