Abstract

This study was conducted to compare the effectiveness of the newly developed electrode pad of ECG with that of a conventional method. To accomplish this, participants who performed both methods on a 46 year old male model were queried and their satisfaction, time, and accuracy were measured by a specialist from 01/06/2018 to 15/06/2018. In the conventional method, a newly developed single pad employing a 12-lead ECG and SIM-Tree was employed. There were 104 total participants in this study (44% medical members). Evaluation of the total procedure time revealed that SIM (mean 65.39 seconds) was more rapid than C (mean 94.38 seconds) (p<0.05). When we evaluated the response after all process, satisfaction with SIM (mean 97.69 seconds) was greater than that with C (mean 68.5 seconds) (p<0.05). Moreover, the intra-class correlation coefficient (ICC) was 0.959 and accuracy was very high (p<0.05). In conclusion, the SIM-Tree was very effective based on procedure time, satisfaction and accuracy when compared with conventional methods.

본 연구의 목적은 기존의 심전도 측정 방법과 새로 발명된 일체형 심전도의 효과에 대한 비교분석을 시행하여 실행효과를 확인하기 위함이다. 이를 위해 46세의 건강한 남성모델을 대상으로 연구에 대한 정보가 없는 심전도 측정 유경험자를 대상으로 진행하였다. 기간은 2018년 6월 1일에서 6월 15일까지 한 기관에 연구와 회의로 내방한 인원 중에서 참여자를 선발하였고 이들에게 12리드형 기존 심전도(C)와 새로 개발된 심전도 방법인 SIM-Tree(SIM)를 간단한 교육 후 시행하여 참가자의 특성, 시행만족도, 각 단계별 시간, 그리고 연구에 대한 정보가 없는 순환기내과 교수의 일치도를 측정 비교하였다. 연구결과, 전체 참여자는 104명이었으며, 전체 시행시간은 SIM이 평균 65.39초로 C의 평균 94.38초에 비해서 통계적으로 빨랐다(p<0.05). 참가자의 만족도 조사에서 SIM이 평균 97.69로 C의 평균 68.5초에 비해서 높게 나타났다(p<0.05). 순환기 내과 교수를 통한 일치도 분석에서 급내상관계수(Intra-class correlation coefficient, ICC)점수가 0.959점으로 충분히 높게 나타났다(p<0.05). 결론적으로 새로 개발 된 SIM-Tree는 시술시간과 만족도에서 기존방법에 비해 효과적으로 나타났고 측정결과에서 기존방법과 높은 일치도를 보였다.
