1. A method for delivering cardiac resynchronization therapy to a patient's heart with a cardiac rhythm management (CRM) device, the steps of the method comprising: a) acquiring signals representing baseline cardiac electrical activity in the patient's heart using electrocardiograph surface-lead electrodes; b) forming a baseline model of ventricular conduction using the signals acquired in step a); c) iteratively modifying the baseline model formed in step b) to minimize ventricular electrical asynchrony; d) generating an updated model of global ventricular conduction that is indicative of ventricular activation wavefront fusion using the iteratively modified baseline model; and e) converting the updated model into pacing control parameters for the CRM device using a QRS hieroglyph morphological framework.
