Abstract
Background
: This study was performed to examine the weak point in EKG reading of family practice residents.

Methods : The data was abstained from comparative analysis between EKG readings of six residents of family medicine and that of one cardiologist.

Results : The EKG readings of rhythm, rate, axis, PR interval, QT interval, amplitude of P wave, and tall T were relatively correct and accordance rates were more than 90 percent. The accordance rates of the EKG reading of diphasity and notching of P wave, fibrillatory P, S₁+R5>35mm of QRS complex, inversion of T wave, elevation of ST segment were about ranged from 70 to 80 percent. The accordance rates of the EKG reading of inversion of P wave, QRS interval, R in V₃<3mm, Q wave, T₁>R6 of T wave, flat T, depression of ST segment were below 70 percent.

Conclusion : Family practice resident's weak points on EKG reading were mainly on the interpretation of inversion of P wave, QRS interval, R in V₃<3mm, Q wave, T₁>R6 of T wave, flat T, depression of ST segment. Hence, More emphasis should be put on the interpretation of these components of EKG.
초록
연구배경 : 이 연구는 가정의학 전공의 심전도 판독에 있어서 미비점을 조사하기 위하여 고안되었다.

방법 : 가정의학과 전공의 6명이 판독한 심전도를 순환기 내과 전문의 1명이 판독한 심전도와 비교 분석 하였다.

결과 : 리듬, 심박수, 축, PR간격, QT간격, P파의 높이, tall T등의 판독은 90%이상의 일치율로서 대체로 정확하였고, P파의 이상성, notching, fibrillatory P, QRS복합체의 S₁+R5>mm,T파의 역위,ST분절의 상승등의 판독은 약 70~80%정도의 일치율을 보였으나, P파의 역위, QRS간격, QRS복합체의 r in V₃<3mm, Q파, T파의 T₁>T6, flat T, ST분절의 하강등의 판독은 70% 이하의 저조한 일치율을 보였다.

결론 : P파의 역위, QRS간격, QRS복합체의 r in V₃<3mm, Q파, T파의 T₁>T6, flat T, ST분절의 하강등은 판독상의 미비점이 있으므로 이부분의 판독에 보다 중점을 두는 심전도 판독 수련이 요구된다고 하겠다.
