Abstract: Objective To investigate the clinical significance of the chronctropic response index(CRI) during the treadmill exercise test in patients with cardiac neurosis. Methods40 patients who had been diagnosed cardiac neurosis received the treadmill test. Based on the test results, decrease of the ST segment, changes of the T wave and CRI were compared between the test group, the coronary heart disease (CHD) group and the control group. ResultsDuring the Treadmill test, the average CRI of 40 patients with cardiac neurosis was 1.41±0.05, which was obviously higher than that of the CHD and control groups（P<0.001）. In the test group, the ST segment was decreased by 0.12±0.04mV, which had no statistical differences from the CHD group but had a significant difference from the control group. Conclusion CRI in the cardiac neurosis group is significantly increased, and CRI＞1.3 conld be of significant value in diagnosis of cardiac neurosis.
