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

Fig 4

Averaged normalized segmental longitudinal strain-time curves of posterior and anteroseptal segments in responders and non-responders to cardiac resynchronization therapy. Error bars represent standard errors. Pre: prior to start of cardiac resynchronization therapy; Post: 9 ± 5 months after the start of cardiac resynchronization therapy
