Mean strain and TTPSD values in each software configuration. Bars indicate mean values (±2 standard deviation) in each software configuration based on 108 patients. a, AP4 strain; b, SAXM strain; c, AP4 TTPSD; d, SAX-M TTPSD. An asterisk indicates a p-value < 0.05. There were many differences in mean AP4 (4C) and SAXM (4D) TTPSD for QLAB 10.5, QLAB 10.8, and TomTec at each frame rate and smoothness setting for the entire cohort. AP4 (Apical four chamber view), HFR (high frame rate), LFR (low frame rate), SAXM (Short Axis Mid papillary muscle); TTPSD (Time To Peak Standard Deviation)
