Table IV.

Comparison of left ventricular systolic functions after treatment in the two groups of patients (%, x±s).

Groups	n	ESSI	SDI	DISPES
Observation group	47	36.54±3.08	5.36±1.25	19.78±3.09
Control group	47	41.38±3.27	7.89±1.62	26.82±3.53
t-test		7.387	8.477	10.288
P-value		<0.001	<0.001	<0.001

ESSI, end-systolic sphericity index; SDI, systolic dyssynchrony index; DISPES, dispersion end systole.
