First pass radionuclide angiocardiography was utilized to calculate right and left ventricular ejection fraction in 74 infants and children. For the synchronization of radionuclide imaging with the cardiac cycle, the peaks and valleys of corrected ventricular time activity curve were adopted as the time reference points instead of R wave of electrocardiogram. Left ventricular ejection fractions obtained by the radionuclide technique correlated well with those derived from the contrast angiographic technique (r = 0.90), but right ventricular ejection fractions correlated less well (r = 0.74). This noninvasive technique appeared useful for evaluation of right and left ventricular ejection fraction.
首次通过放射性核素心血管造影术被用于计算74例婴幼儿的左右心室射血分数。为使放射性核素成像与心动周期同步，采用校正后的心室时间-活性曲线的峰谷作为时间参考点，而非心电图的R波。放射性核素技术测得的左心室射血分数与对比血管造影技术测得的结果相关性良好（r = 0.90），但右心室射血分数的相关性稍差（r = 0.74）。这种非侵入性技术似乎有助于评估左右心室射血分数。
