Official Title: A Study to Observe the Change of the Biological Signal (Heart Rate) During the Combined Pituitary Stimulation Test
Brief Summary:
Several studies have been reported that heart rate is known to be associated with prognosis in chronic diseases and acute diseases. For example, a decrease in heart rate following myocardial infarction may lead to a higher mortality rate. It is also known to predict heart failure, diabetic neuropathy, and even depression.
The combined pituitary function test artificially induces hypoglycemia to observe the secretion of pituitary hormone. The degree of change in heart rate during hypoglycemia can predict the adequacy of the test, and heart rate can be changed according to the characteristic of the tumor. Also, the prognosis can be predicted based on this.
In our study, we used a licensed device approved by KFDA (Korea Food and Drug Administration) to measure heart rate variability in patients with pituitary adenoma.
