Figure 2 Septal-to-posterior wall motion delay (SPWMD) and septal-to-lateral delay after long-term right ventricular pacing. For left ventricular dyssynchrony, a cutoff value of SPWMD 130 ms (dashed line), and septal-to-lateral delay 65 ms (solid line) was used. There is a good agreement between SPWMD and septal-to-lateral delay. In only 4 patients, there was a disagreement between SPWMD and septal-to-lateral delay.
