Patent ID: 8562532

Claim:
A non-transitory computer-readable medium having computer-executable instructions to cause a computer or computer-based system to perform a method for analyzing cardiac wall motion of first and second cardiac regions using cardiac wall motion contours detected an echocardiogram, the method comprising: receiving regional displacement magnitudes calculated for the first and second cardiac regions over one cardiac cycle based on cardiac wall motion contours detected from the echocardiogram; generating first and second regional displacement curves based on the regional displacement magnitudes calculated for the first and second cardiac regions, respectively, the first and second regional displacement curves each being a plot of regional displacement magnitude verses time over the cardiac cycle; providing a common magnitude reference to the first and second regional displacement curves; averaging each of the first and second regional displacement curves over a predetermined number of cardiac cycles; smoothing the averaged first and second regional displacement curves; and computing a relative phase representing a phase relationship between the first and second regional displacement curves based on a frequency analysis using the smoothed and averaged first and second regional displacement curves, the relative phase indicative of a cardiac wall motion asynchrony.
