Eliminating Discrepancies Between Assessments of Left Ventricular Wall Motion on Echocardiograms / 日本農村医学会雑誌

ABSTRACT

Echocardiographic assessment of wall motion is prone to interrater variability because it requires subjective visual evaluation. Echocardiography technicians were divided into 2 groups by years of experience, and their assessments of left ventricular wall motion on previously recorded echocardiograms were scored and compared. Scores did not differ within the more experienced group but differed significantly between technicians in the less experienced group. However, this difference disappeared after 3 months of training. This suggests that training can eliminate discrepancies between technicians, even inexperienced ones, in a relatively short period of time.
