AF is a 55-year-old woman who had been experiencing heart palpitations, a throbbing headache, sweating, pain in the abdomen, nausea and vomiting. Because these symptoms had failed to subside, she went to see her primary care physician. A urinalysis revealed the presence of catecholamines and their metabolites. A subsequent CT scan confirmed the presence of a tumor in the adrenal medulla. Surgery to remove the tumor was scheduled What is your diagnosis of this patient? a. pheochyomocyoa b. Would you expect this patient to have tachycardia or bradycar dia? Why? What auto nomic receptors are involved with this change in heart rate? c. the blood pressure be What autonomic receptors are involved wit re likely to be lower or higher than normal for this patient? Why? s h the change in blood pressure? autonomic receptors are

Explanation / Answer

b.patient develops tachycardia,because of the anxiety related to the disease and plan of surgery.
autonomic receptors involved in this increased heart rate are Beta adrenergic receptors .

c.blood pressure become higher than the normal,because of tension related to the surgery and outcome.
Alpha adrenergic receptors plays an important role in the regulation of blood pressure.when the alpha receptor is stimulated by epinephrine or norepinephrine the arteries constrict and causes to increased blood pressure.
