Table 1 Mean ± standard deviation of SDI values from different groups.

From: The effect of septal basal segments in the assessment of systolic dyssynchrony index

Group Size All segments No septal base P-value
Asymptomatic 292 5.8 ± 2.5% 4.2 ± 1.8% < 0.001
Hypertrophy 12 6.5 ± 4.9% 3.8 ± 2.7% 0.04
Heart Failure 24 11.7 ± 5.6% ** 10.6 ± 5.5% ** 0.007
  1. Two measurements were performed on each group, one with all segments included and the other omitting the septal base (S2 and S3) segments. P-value column was paired t-test between two measurements. Unpaired t-test between a particular group and the asymptomatic group was performed and marked with ** for P<0.001.
