Stress Test Dobutrex

INDICATIONS: Abnormal EKG.

STRESS TECHNIQUE: Dobutrex was infused at 10 µg/kg/minute increasing in three-minute intervals. Maximum heart rate was 113. No significant EKG changes noted.

NARRATIVE: Uptake of radioisotope was adequate in all views. There was an inferior abnormality noted in the short axis view from 4:00-6:30. In the vertical long axis view, there was an inferior abnormality with minimal improvement. The horizontal long axis view had a lateral apical abnormality with no change.

WALL MOTION: The left ventricle was of normal size and motion. All wall segments moved normally.

EJECTION FRACTION: 72%.

CONCLUSIONS:
1. Negative Dobutrex stress test.
2. Normal wall motion and ejection fraction.
3. Abnormal nuclear scan consistent with possible underlying ischemic heart disease. Clinical correlation suggested.
