Abstract
ECG gated blood pool scintigraphy (EGBP) is not always valid for the patients with atrial fibrillation (AF), since they have wide variability in cardiac cycle length (CL). To evaluate the left ventricular (LV) function during AF by EGBP, we devised a new processing algorithm to construct multiple gated images discriminated by preceding R-R interval (PRR) from the data acquired in list mode. 18 patients with AF were studied as to; 1) How affect the PRR on cardiac indices such as EF, TES, PER or TPER, 2) Comparison with conventional method getting all CL data, 3) LV filling curves derived by plotting EDV against PRR, 4) The slope and position of LV function curves (LVFC) derived by plotting SV against EDV. In most cases, EF, PER and TES were increased with longer PRR, and those by conventional method nearly corresponded to the average values obtained by our new method. Impairment of ventricular filling was demonstrated in the cases of mitral stenosis and constrictive pericarditis. LVFC of CHF group was situated at right and downward to controls, and left and upward shift was observed after treatment. The slope of LVFC was reduced in relation to the progression of NYHA's functional class. In
