Radionuclide ventriculographic findings in pericardial effusion

We present a patient with a large pericardial effusion, in whom the first-pass radionuclide ventricu-logram demonstrated rocking motion of the left ventricle and apparent asynergy of the inferior wall. These abnormalities disappeared after removal of the fluid. Inspection of the cinematic display of the images was useful in explaining the apparent asynergy of the inferior wall.
