Table 3 Image quality for analysis of LVEF

From: Global longitudinal strain is a more reproducible measure of left ventricular function than ejection fraction regardless of echocardiographic training

Echocardiographer Good Fair Poor
Trainee 38 (80.9) 4 (8.5) 5 (10.6)
Expert 38 (80.9) 6 (12.8) 3 (6,4)
  1. Categorical data are presented in numbers (%). LVEF = left ventricular ejection fraction. Good = > 75% of visible endocardium. Fair = 60–74% of visible endocardium. Poor = less than 60% of visible endocardium
