Abstract:
1. A method for optimizing cardiac resynchronization therapy comprising: a. sensing a signal proportional to a blood pressure development of a patient; b. determining a stroke volume surrogate from the sensed signal proportional to blood pressure by deriving a signal characteristic that varies proportionally to stroke volume variations; c. at least temporarily storing in a readable storage medium at least a one of the following: the signal, the stroke volume surrogate, the signal characteristic d. applying a plurality of A-V-V timing schemes and repeating steps a., b., and c. for at least a subset of said plurality of A-V-V timing schemes; and e. identifying an optimal A-V-V timing scheme corresponding to the highest magnitude stroke volume based on the stroke volume surrogate for one of said plurality of A-V-V timing schemes.
