Claim Text:
1. A method of cardiac pacing comprising: (a) determining a baseline rhythm using a plurality of body-surface electrodes; (b) determining a set of baseline functional electrical metrics in response to determining the baseline rhythm; (c) delivering resynchronization pacing using a right ventricular electrode and a left ventricular electrode or delivering the resynchronization pacing using only a left ventricular electrode; (d) determining a set of functional electrical metrics relating to cardiac depolarization and repolarization in response to resynchronization pacing; (e) determining whether relative reduction of at least one functional electrical metric from the set of functional electrical metrics in step d exceeds X % of its corresponding value from the set of baseline functional electrical metrics in step (b); (f) determining whether an absolute value of at least one electrical metric from the set of the functional electrical metrics in step (d) is less than Y ms; and (g) determining that a site is responsive to cardiac resynchronization therapy (CRT) in response to determining whether steps (e) or (f) are met.
