Temporary sequential biventricular pacing (BiVP) is a promising treatment for postoperative
cardiac dysfunction, but the mechanism for improvement in right ventricular (RV) dysfunction
is not understood. In the present study, cardiac output (CO) was optimized by sequential
BiVP in six anesthetized, open-chest pigs during control and acute RV pressure overload
(RVPO). Ventricular contractility was assessed by the maximum rate of increase of
ventricular pressure (dP/dt max). Mechanical interventricular synchrony was measured by …
