INDICATIONS:,  Atrial fibrillation, coronary disease.,STRESS TECHNIQUE:, The patient was infused with dobutamine to a maximum heart rate of 142.  ECG exhibits atrial fibrillation.,IMAGE TECHNIQUE:,  The patient was injected with 5.2 millicuries of thallous chloride and subsequently imaged on the gated tomographic SPECT system.,IMAGE ANALYSIS:,  It should be noted that the images are limited slightly by the patient's obesity with a weight of 263 pounds.  There is normal LV myocardial perfusion.  The LV systolic ejection fraction is normal at 65%.  There is normal global and regional wall motion.,CONCLUSIONS:,1.  Basic rhythm of atrial fibrillation with no change during dobutamine stress, maximum heart rate of 142.,2.  Normal LV myocardial perfusion.,3.  Normal LV systolic ejection fraction of 65%.,4.  Normal global and regional wall motion.radiology, dobutamine stress test, atrial fibrillation, lv myocardial perfusion, lv systolic ejection fraction, coronary disease, dobutamine, ejection fraction, gated tomographic spect system, thallous chloride, wall motion, stress, fibrillation, atrial
