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

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

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

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.
