We assessed left ventricular ejection fraction 47 times in 21 patients with sinus rhythm by a portable non-imaging nuclear probe. After 99mTc blood pool labelling, left ventricular ejection fraction was determined by probe in two different ways: on a beat-to-beat basis, and by the so-called ventricular function mode, based on the gated equilibrium principle, and subsequently compared with left ventricular ejection fraction measured by gated equilibrium radionuclide angiocardiography using a gamma camera. Left ventricular ejection fraction by probe correlated well with left ventricular ejection fraction by gamma camera: beat-to-beat versus gamma camera: r = 0.90, y = 0.75x + 0.12; ventricular function versus gamma camera: r = 0.88, y = 0.87x + 0.08. Also, left ventricular ejection fraction values determined by the two probe methods correlated closely: r = 0.97, y = 0.83x + 0.07. Compared with the gamma camera, the probe overestimated slightly the small values of left ventricular ejection fraction and underestimated high values. Correct determination of left ventricular ejection fraction by a non-imaging probe depends on correct positioning over the left ventricle and selection of a proper background activity level. The main application of this instrument is probably non-invasive bedside determination and monitoring of changes of left ventricular function occurring spontaneously or caused by cardiac arrhythmias or treatment with cardiac drugs. |
