Claim Text:
1. A method for evaluating and treating a temporal ventricular desynchronization in a heart of a patient, the method comprising: receiving a signal representative of a blood flow in a left chamber of the heart; receiving a signal representative of a displacement of a left ventricle of the heart; determining an instant of closure of an aortic valve using the signal representative of the blood flow in the left chamber; determining a peak of contraction of the left ventricle using the signal representative of the displacement of the left ventricle; calculating a temporal shift between an instant of the peak of contraction of the left ventricle and the instant of closure of the aortic valve; selecting a current stimulation configuration based on the calculated temporal shift; and delivering stimulation pulses to be applied to electrodes respectively implanted in at least one right ventricular pacing site and at least one left ventricular pacing site according to the current stimulation configuration based on the calculated temporal shift.
