Fig. 7From: Comparison of strain parameters in dyssynchronous heart failure between speckle tracking echocardiography vendor systemsSchematic overview of septal strain pattern categorization for Philips derived echocardiographic images, analysed with Philips QLAB and TomTec 2DCPA. Agreement between vendor-specific (Philips QLAB) and vendor-independent (TomTec 2DCPA) software is given in the grey square, with corresponding Cohen’s kappa given underneath. Both analyses were performed twice (1st and 2nd), to determine the intra-observer agreement. Arrows indicate the reclassification of patients between vendors or between the first (1st) and second attempt (2nd). LBBB-1: double-peaked systolic stretch, LBBB-2: predominant stretch, and LBBB-3: pseudo normal shorteningBack to article page
