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.
