This study demonstrates that radionuclide angiocardiography provides a simple and noninvasive
approach for evaluation of myocardial function. Previous work concerning myocardial …

To determine if abnormalities in left ventricular function precede angina pectoris and
electrocardiographic evidence of myocardial ischemia, we used radionuclide angiocardiography to …

Radionuclide angiocardiography provides accurate hemodynamic information during maximal
exercise in erect subjects. Cardiac function was studied with this noninvasive technique …

Left ventricular function during brief (10 minutes) and prolonged (2 hours) upright bicycle
exercise was studied in nine young men. Left ventricular ejection fraction and volumes and …

This study introduces a new method for calculating actual left ventricular volumes and cardiac
output from data recorded during a single transit of a radionuclide bolus through the heart, …

The diagnostic accuracy of the Bruce multistage exercise treadmill test (ETT) and changes in
left ventricular function assessed by radionuclide angiocardiography (RNA) during rest and …

Disorders of the peripheral vascular system often are associated with heart disease which
may increase operative risk. The purpose of this study was to investigate the clinical …

Ventricular function was measured by radionuclide angiocardiography during rest and exercise
in patients before and approximately 4 months after aorta-coronary bypass grafting. The …

METHODS Phantom studies. A sphericalrubber ball (phantom) with a 2-mm wall thickness
and a 5-cm internal radius was filled with 350 ml of water containing 5 mCi of pertechnetate (…

Three noninvasive radionuclide techniques are of value in diagnosis and management of
patients with myocardial ischemia. Thallium is an analogue of potassium that is distributed in …
