The Relationship Between Coronary Heart Disease and Autonomic Nervous Impulse Abnormality;

Heart rate variability is an index which reflex the function of cardiac autonomic nervous system, thus it can be used on the study of psychophysiological response of patients with anxiety neurosis.

Objective To study the relationship between the functional change of autonomic nervous system(ANS)and acute mountain sickness(AMS)after urgent entering into the altitude,so as to explore the effect of ANS on the onset of AMS and to seek possible path to prevent AMS.

Much information about the status of autonomic nervous system can be obtained by means of examining patients heart rate.

Objective To observe the changes of heart rate variability (HRV),after intervention with spironolactone,and explore the effects of spironolactone on autonomic nervous system,ventricular remodeling and its safety.

Objective To evaluate the regional anatomy between the abdominal autonomic nerves including the abdominal aortic plexus (AAP) and the inferior mesenteric artery (IMA), and explore the safe ligation point on the IMA and the optimal dissection method to avoid autonomic nerve injuries.
