Left Ventricular Longitudinal Function Assessed by Speckle Tracking Ultrasound from a Single Apical Imaging Plane
Figure 5
Apical (a) and subcostal (b) four-chamber view from the same patient. Segmental peak systolic strain values are indicated. Apex of the heart can be difficult to recognize in the subcostal view and peak systolic strain values appear to be significantly higher at the apex of the subcostal view than the apical view. See text for further explanation.
