Method and apparatus for quantification of cardiac wall motion asynchrony |
摘要 |
A phase analysis technique provides for quantification of regional wall motion asynchrony from endocardial border contours generated from two-dimensional echocardiographic ventricular images. The technique produces results including a degree of radial ventricular asynchrony in heart failure patients with ventricular conduction delay to predict a magnitude of contractile function improvement with pacing therapy. Quantification of change in ventricular regional wall motion asynchrony in response to a therapy provides for a means to identify candidates to receive the therapy and quantitatively predict the benefit of the therapy. Quantification of changes in ventricular regional wall motion asynchrony in response to a sequence of therapies provides for a means to determine an approximately optimal therapy for an intended patient response.
