Fig. 5

Mean strain values in each software configuration, by group. Mean values are presented (±2 standard deviation) by group (36 patients in each). a) AP4 strain; b) SAXM strain. An asterisk indicates a p-value < 0.05. AP4 Apical four chamber view, FR (frame rate), LS (Low quantification smoothness setting), HS (High quantification smoothness setting), MS (Medium quantification smoothness setting), SAXM (Short Axis Mid papillary muscle). Dark gray bars (group 1) are patients with normal hearts; white bars (group 2) are patients with ventricular paced rhythms; light gray bars (group 3) patients have flattened septal wall
