Research on Strain and Strain Rate in Left Ventricular Walls in Healthy Human Being

To detect how strain and strain rate change in the left ventricular walls in the healthy human being. Methods: Thirty-eight healthy people were selected and examined by echocardiography, then strain and strain rate were compared among the basal, middle and apex segments and among the different walls. Results: Although strain and strain rate declined from basal segment to apex, there was no statistical difference. There was also no significant difference between the same segments of the different walls. Conclusion: There was no statistical difference of strain and strain rate between the different segments and the different walls.
