Extracardiac activity (bowel) noted in the rest and stress studies (arrows with "B").
Note : 2-3 mm horizontal ST depression in the inferior and lateral leads were noted in the stress study.
Comments:
In patients with stress-induced ST abnormalities, high exercise capacity, and peak heart rate >85% of predicted, no associated chest pain, and no perfusion abnormalities, the post-test probability of ischemic heart disease is very low and the prognosis very good.
Stress ECGs specificity in most studies is around 80%.
False-positive stress ECG includes: Digoxin, LVH, early repolarization syndrome, intraventricular conduction abnormalities, hyperventilation...among many.
The etiology in this case remains unclear.
At follow up, a month after the test, the patient was doing well.
