Stress Test Dobutamine

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.
