X. Wang, Chen, G. Y., Yang, S. S., Tian, Y., Ge, T., Qin, H., Han, W., and Chang, H. Y., Effects of high thoracic epidural anesthesia on ischemic cardiomyopathy cardiac function and autonomic neural function, vol. 13, pp. 6813-6819, 2014.

We aimed at observing the effects of high thoracic epidural anesthesia (HTEA) on cardiac structure and function, heart rate variability (HRV), and QT interval variation (QTV) in ischemic cardiomyopathy (ICM) patients with chronic heart failure. We divided 30 ICM patients into HTEA (N = 16) and control (N = 14) groups.The control group was treated with medication, and the HTEA group was treated with HTEA and medication for 4 weeks.
