From: Echo-driven V-V optimization determines clinical improvement in non responders to cardiac resynchronization treatment

Figure 4

Panels A, B and C show TSI in the apical 4 (A), 2 (B) and 3 chamber (C) views with LV pre-excitation of 5 ms and panels D-F are corresponding views with LV pre-excitation of 10 ms in a 67 year old male with non ischemic cardiomyopathy post CRT. Note improvement in lateral, right ventricular free wall, inferior and posterior wall delay with LV pre-excitation of 10 ms. Some delay in interventricular septal contraction (red in distal septum in panel D and yellow in anterior septum in panel F) occurred with LV pre-excitation of 10 ms. Also note the narrowing of QRS complex with LV pre-excitation (white arrows C and F).
