Effects of sympathetic stimulation on ventricular refractory periods in cats with acute coronary artery ligation

Summary Ventricular refractory periods shorten in the ischemic area following acute coronary artery ligation. Subsequent bilateral sympathetic nerve stimulation reduces disparity in refractory periods across normal, border (peri-ischemic) and ischemic areas.This work was supported by NIH Research Grants HL 19044 and HL 21735, NIH Biomedical Research Support Grant DRR No. S07-05363 and a Grant-in-Aid from the American Heart Association, Florida Affiliate, Broward County Chapter.
