Why the study?
Are circumferential and longitudinal peak strain and systolic strain rate sensitive to acute changes in load in human subjects?
Are circumferential and longitudinal peak strain and systolic strain rate sensitive to acute changes in load in human subjects?
Load dependency is an important factor that must be considered when applying strain and strain rate as indices of systolic function.
Acute load changes must be considered in strain interpretation; leaves open standardized load-correction methods.
Circumferential and longitudinal peak strain and systolic strain rate are sensitive to acute changes in load, an important factor that needs to be considered in their application as indices of systolic function.
