The 17-Segment model of heart

• Dark red = normal

• Lighter red = longitudinal hypo- to akinesia

• Blue = akinesia, darker blue also dyskinesia (longitudinal)

• Negative values around -20% are normal GLS values

• Bullseye with corresponding myocardial segments

• If 2 or more segments are not measured nicht gemessen werden (e.g. image quality) the GLS should not be measured
