Explanation / Answer

Rapid heart rate,high blood pressure etc are the symptoms of Sympathetic nervous system activity. They do so to prepare body for emergency situations by releasing hormone adrenaline.

So, this endocrine disorder is mimicking the Sympathetic branch of of ANS.

The symptoms are same because the tumor in the adrenal gland hyperactivates the adrenal medulla and this leads to increased secretion of catecholamine hormones like adrenaline.
