The article presents the case of a one-year-old boy who was hospitalized for episodes of intense sweating, pallor, mild shortness of breath and hypertension.

The case highlights the importance of considering parent-reported symptoms and monitoring blood pressure in infants with suspected adrenergic syndrome.
