Radionuclide cineangiography during stress.
A "real-time" ECG-gated scintigraphic image system was developed at NIH, Bethesda. This system presents in real-time manner 1) an image sequence, that spans a complete heart cycle, 2) a regional time activity curve, in which later distolic phenomena are correctly portrayed, and 3) a beat length distribution function. This system is suitable especially for stress investigations. Normal subjects showed an increase of ejection fraction, whereas patients with CAD revealed a decrease of EF.
