Figure 1 Final activation map of coronary sinus tributary veins during spontaneous rhythm and final position of right (RV) and left ventricular (LV) leads in 2 views (corresponding to left and right anterior oblique views) (top). In the color range, blue and purple represent the latest activated sites with respect to the onset of QRS. Electrical signals from RV apical lead, surface lead, and distal and proximal dipoles of quadripolar LV lead, respectively (bottom).
