A method which does not require an online computer has been developed to measure left ventircular ejection fraction from a bolus of 99mTc-pertechnetate. The passage of the bolus through the cardiac chambers was imaged using a gamma camera and recorded on video tape. On replay a region of interest co
The left ventricular ejection fraction (EF) was studied in 17 healthy volunteers with a new ambulatory left ventricular function monitor. Heart rate, EF, and blood pressure measurements were made during rest, a psychiatric stress interview, cold exposure, exercise, and eating. An increase in EF was
Background. A method that uses single photon emission computed tomography (SPECT) equilibrium radionuclide angiocardiography (ERNA) to measure right ventricular (RV) and left ventricular (LV) volumes (in milliliters) and ejection fraction (EF) is described. Methods and Results. We recorded 35 paired
