Abstract
A method and apparatus for pacing left and right ventricles of the heart involve measuring one or both of a right ventricular (RV) pressure and a left ventricular (LV) pressure, and computing a parameter developed from one or both of the RV and LV pressure measurements. The parameter is indicative of a degree of left and right ventricular synchronization. The parameter is assessed, and an interventricular (V-V) delay is adjusted in response to the parameter assessment. The V-V delay is adjusted to effect a change in the parameter that improves synchronization of the right and left ventricles. The computed parameter is a parameter indicative of hemodyamic state, such as a PP Loop or a pre-ejection period.
