Abstract
INTRODUCTION
Abnormalities of the left ventricular diastolic function are
common in a variety of disease states and have recently been
recognised as a cause of symptoms in some patients even in the
presence of normal systolic function (Soufer et al., 1985).
For the most clinical situations, the LV ejection fraction
provides a simple easily interpreted and generally reliable
measure of LV systolic function.
In contrast a simple single measure of LV diastolic
function has been derived from invasive and more recently
non invasive tests. These indices quantitate aspects of the rate
of LV relaxation, the passive properties of the LV and the
pattern of LV filling.
Knowledge of how heart fills is necessary in order to
understand the clinical significance of LV diastolic performance
and properly interpret and apply these diagnostic measures.
(Santamore et al., 1986).
Doppler Echocardiography 1s a non invasive and easily
performed technique that provides important information
about the diastolic function of the LV by analysis the
transmitral doppler flow.
Radionuclide angiography is another recent non invasive
technique that has been advocated to evaluate the LV diastolic
function by using time activity curve.
