Longitudinal Lagrangian Strain Rate |
Rate of change of longitudinal strain over time. |
|
130673
|
Mechanical Dispersion |
The standard deviation of the time to peak longitudinal strain value for different myocardial segments. Typically assessed over 18-segments of the left ventricle. |
|
130672
|
Time to Peak Longitudinal Lagrangian Strain |
The time from the beginning of the interval to the time of the peak longitudinal Lagrangian strain. |
|

|
Peak Longitudinal Lagrangian Strain |
Peak value of longitudinal Lagrangian strain during an identified interval, such as systole or a full cardiac cycle. |
|
130678
|
Circumferential Lagrangian Strain Rate |
Rate of change of circumferential Lagrangian strain over time. |
|
130677
|
Circumferential Lagrangian Strain |
Lagrangian strain tangential to the reference contour, perpendicular to the longitudinal strain, with positive values in the counterclockwise direction when viewed from the apex. |
|
130676
|
Radial Lagrangian Strain Rate |
Rate of change of radial Lagrangian strain over time. |
|
130675
|
Radial Lagrangian Strain |
Lagrangian strain in the wall of a cavity perpendicular to the longitudinal strain and towards the center of the cavity. |
|
130670
|
Longitudinal Lagrangian Strain |
Lagrangian strain parallel to the reference contour (i.e. in the longitudinal direction) calculated as: SL(t)=(L(t) -L0)/L0, where L(t) is the length at a given point t in time and L0 is the reference length at the reference time t0.Strain values are negative with shortening. Due to the common convention of using end-diastole as the t0 reference time, echocardiography strain values are typically negative. |
