Figure 2From: Cardiovascular magnetic resonance myocardial feature tracking detects quantitative wall motion during dobutamine stressCircumferential and radial strain in respect to changes of left ventricular ejection fraction. The figure shows changes in circumferential and radial strain in respect to changes of left ventricular ejection fraction (EF) at rest and with dobutamine stress (10 and 20 μg/kg-1/min-1). Values expressed as mean with standard deviation. LV = left ventricle, EF = ejection fraction.Back to article page
