FIGURE 2.

Representative example of effects of atrioventricular delay (AVD) and interventricular delay (VVD) optimization on mean arterial pressure (MAP). Standard errors of averaged duplicate determinations shown in brackets. A, Best AVD according to MAP was 240 ms. Worst and nominal AVDs according to MAP are labeled. B, Best, worst, and nominal VVDs according to MAP are labeled. BiPACS, Biventricular Pacing After Cardiac Surgery; RV, right ventricle; LV, left ventricle; VVD, interventricular delay.
