How do catecholamines increase blood pressure?
Catecholamines are released in times of stress. They make your heart beat faster with greater force and narrow the blood vessels, causing a rise in blood pressure. The beta1 effects of catecholamine on the heart are due to an increase in intracellular concentration of cyclic-AMP.
What causes hypersecretion of catecholamine?
Pheochromocytoma, also called chromaffinoma, tumour, most often nonmalignant, that causes abnormally high blood pressure ( hypertension) because of hypersecretion of substances known as catecholamines ( epinephrine, norepinephrine, and dopamine ). Usually the tumour is in the medullary cells of the adrenal gland; however, it may arise from extra-adrenal chromaffin tissue, which may be located in the sympathetic nervous system adjacent to the vertebral column anywhere from the neck to the
