Abstract
The interpretation of wall motion is an important component of echocardiography but remains a source of
variation between observers. It has been believed that automated quantification of left ventricular (LV) systolic
function by measurement of LV systolic strain from speckle-tracking echocardiography might be helpful. This
multicenter study of nearly 250 volunteers without evidence of cardiovascular disease showed an average LV peak
systolic strain of -18.6 ± 0.1%. Although strain was influenced by weight, blood pressure, and heart rate, these
features accounted for only 16% of variance. However, there was significant segmental variation of regional strain
to necessitate the use of site-specific normal ranges.
