Inexpensive ventricular phantom for ECG-gated equilibrium studies.
A simple ventricular phantom has been constructed to validate calculations of ejection fraction in radionuclide ECG-gated equilibrium studies. The R-wave stimulator constructed from one integrated circuit can also be used as a stand alone device for testing computer interface and cable connections for the ECG R-wave synchronizer input.
