Research on Strain and Strain Rate of Left Ventricular Wall in Forty Normal Subjects

Objective To investigate strain and strain rate of left ventricle wall in normal healthy subjects.Methods Forty healthy adults were enrolled in the study,the strain and strain rate were compared among the basal,middle and apex segments and among the different walls.Results Strain were decreasing from basal to apex segment in anterior wall,anterior septal,post septal,lateral wall and post wall.There was no significant difference in inferior wall.Post septal strain value was the highest in all left ventricular walls.The significant difference in same wall of the different segments is more significant than the same segment of the different walls.The significant difference of strain rate in the same segment of the different walls was present in the mid and apex segment.Conclusion Whatever in same wall of the different segments or the same segment in the different walls perhaps there is no clear regular distribution model.
