From: Sequential biventricular pacing improves regional contractility, longitudinal function and dyssynchrony in patients with heart failure and prolonged QRS

Figure 1

Tissue Doppler Imaging curves with systolic maximal velocity (SMV) preoperatively ( left ) and after implantation of CRT device ( right ), at best VV-interval (sequential pacing LV lead 40 ms before RV lead in this patient), showing improved systolic function, i.e. higher velocity. Signs of less dyssynchrony (arrows) are also seen.
