Evaluation of cardiac function during stress exercise provides important information
unavailable from studies performed at rest. A dequate data are difficult to obtain during …

Study Design Studies were obtained on two separate days, with subjects randomly allocated
to perform either bicycle or treadmill exercise at their first session. Forced balancing of …

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

Background Treadmill testing is usually preferred over cycle ergometry because of the
greater sensitivity in diagnosing coronary artery disease. Treadmill testing has only recently …

To determine whether the temporal sequence of imaging could influence the results of
exercise radionuclide angiography, 15 healthy volunteers were studied at rest, during peak …

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

Exercise was performed on an isokinetic bicycle ergometer (Fitron, MA) beginning at 200
kilopond-meters per minute and increasing 100 kilopond-meters/minute until leg exhaustion …

Planar equilibrium radionuclide angiography (ERNA) is used to determine global and
regional measures of ventricular function (primarily left ventricular [LV] function) at rest …

An electrocardiographic-triggered radiographic technique for obtaining a single image of the
heart at both end-systole and end-diastole was used in conjunction with upright bicycle …

We investigated the factors that determine the left ventricular ejection fraction response to
exercise in 57 middle-aged, untrained patients with angiographically normal coronary …
