Figure 3.
The response numbers when left ventricular lead was at the site with a different match incorporating left ventricular systolic and diastolic dyssynchrony. The green bars stand for responders and blue bars stand for non-responders. In the first category, CRT response in patients whose LV lead positions were in both the latest three contracting and latest three relaxing segments (n = 18), and only 1 case had no response. In the fourth category, CRT response in patients whose LV lead positions were neither in the latest three contracting nor latest three relaxing segments (n = 15), and totally 14 cases had no response (P < 0.000).
