The present study is conducted to find out the changes in heart rate in response to change in the body posture from supine to standing in hypothyroid patients. Heart rate response to standing is one of the autonomic function tests to assess the integrity of the autonomic nervous system. Autonomic dysfunction affects 50% of hypothyroid patients. Consented 60 adult (20 -50 years), 30 were patients with hypothyroidism and 30 controls. Heart rate was recorded before and after changing body posture from supine to standing. The data of the patients was compared with controls and statistically analyzed. Heart rate in hypothyroid patients (4.633±14.4) is less than the controls (16.266±19.8). The change is significant at p<0.004. Our findings showed that decreased levels of thyroid hormones in hypothyroid patients alter the autonomic activity on heart.
