LV = left ventricular; TQ = tracking quality.

  • Inferior was significantly different from all other walls (p < 0.001 except anterior p = 0.02), in the comparison of walls at all levels.

  • Posterior was significantly different from all other walls (p < 0.0001). In the comparison of levels in all walls, each level was significantly different (p < 0.0001).
