From: Strain-time curve analysis by speckle tracking echocardiography in cardiac resynchronization therapy: Insight into the pathophysiology of responders vs. non-responders

Fig 2

Individual (a) and averaged (b) strain-time curve of basal lateral segment in the responders prior to cardiac resynchronization therapy. a Individual segmental strain-time curves, normalized for systolic duration, obtained from basal lateral segment in the responders group prior to start of cardiac resynchronization therapy. Systolic duration is defined as the time from the mitral valve closure to aortic valve closure. b Averaged normalized segmental strain-time curve (with error bars indicating standard error) obtained by averaging the data shown in Panel a. Arrows depict the time points corresponding to mid systole (50 %), end-systole (100 %) and post-systole (125 %). CRT, cardiac resynchronization therapy
