Abstract
Techniques are provided for exploiting left atrial pressure (LAP) measurements to determine various ventricular mechanical and electromechanical contraction intervals and for evaluating ventricular dyssynchrony based on those intervals. In one example, LAP measurements are combined with right ventricular pressure (RVP) measurements to determine the interventricular mechanical delay, which is the primary parameter representative of ventricular dyssynchrony. Other intervals determined based, in part, on LAP measurements include the electromechanical delay for the left ventricle (LV), as well as the LV systolic and diastolic intervals. Techniques are also described herein for detecting various RV intervals including the electromechanical delay for the RV, as well as the RV systolic and diastolic intervals.
