A method and apparatus for optimizing cardiac resynchronization therapy are provided. An iterative optimization procedure is performed to test the systolic hemodynamic effects of varying A-V-V timing schemes. The hemodynamic effect is assessed based on a surrogate of stroke volume. The stroke volume...http://www.google.com/patents/US6871088?utm_source=gb-gplus-sharePatent US6871088 - Method and apparatus for optimizing cardiac resynchronization therapy
