Figure 13From: Echocardiographic quantification of myocardial function using tissue deformation imaging, a guide to image acquisition and analysis using tissue Doppler and speckle tracking Bulls-eye figure of peak systolic strain values in the left ventricle before CRT device implantation. Red = normal strain values, pink = reduced value, light pink = severely reduced values. Global strain of the left ventricle is -10.1%.Back to article page
