title: Dissociation of left ventricular end-ejection from end-systole: scintigraphic evaluation and implication.
abstract: We have measured the extent and evaluated afterload dependence of temporal dissociation of left ventricular end-ejection from end-systole using count rate dependent scintigraphic method. Good predictability of the dissociation (y) especially in the lower ranges of afterload (x) has been demonstrated (y = 9.1 x -763: r1 0.72: r2 0.55: r3 0.86). Role of the dissociation as the corrective parameter in count rate dependent scintigraphic method for evaluation of left ventricular contractile function (in contradistinction to the ejection function) has been discussed.
