Abstract/OtherAbstract:
Segmental early relaxation, a form of left ventricular asynchrony, refers to lengthening of a myocardial segment before mitral valve opening. This phenomenon may occur in normal and diseased hearts; when it is seen in a diseased ventricle it may occur in either the abnormally contracting segment or the normal segment. Experimental data indicate that altered loading conditions, especially nonuniform distribution of load or functional inhomogeneities (as may occur with regional ischemia), or both, may result in asynchronous relaxation of the left ventricle.
