[Determination of left ventricular function using nuclear medicine methods].
ECG-gated blood-pool scintigraphy with multiple gating acquisition is a good tool for evaluation of global and regional ventricular function. During exercise there is an average increase of ejection fraction of about 13.4% compared with rest ejection fraction in patients with normal ventricular function. A decrease or insufficient increase of ejection fraction by exercise is due to myocardial ischemia. After administration of isosorbiddinitrat in retard preparation there is an increase of ejection fraction of about 7%, lasting at least for 12 hours.
