Patent ID: 7974694

Claim:
A system for use with an echocardiographic sensor and an echocardiographic machine adapted to record an echocardiogram, the system comprising: a controller including: a therapy protocol synthesizer adapted to generate a sequence of therapy parameters; and an automatic therapy protocol execution module adapted to time delivery of a sequence of therapies each using at least one parameter of the sequence of therapy parameters; a therapy circuit, coupled to the controller, to deliver the sequence of therapies; and a cardiac wall motion evaluation module adapted to receive the echocardiogram recorded by the echocardiographic machine during the delivery of the sequence of therapies and calculate parameters representative of degrees of cardiac wall motion asynchrony each associated with one therapy of the sequence of therapies based on a portion of the echocardiogram recorded during the delivery of the one therapy of the sequence of therapies; wherein the cardiac wall motion evaluation module further comprises a therapy decision module coupled to the phase computer, the therapy decision module adapted to determine one or more approximately optimal pacing parameters based on the relative phase.
