Chronic kidney disease is highly prevalent and is associated with cardiovascular disease. Paricalcitol protects from some renal and cardiovascular complication. However, its electrophysiological effect during myocardial ischemia-reperfusion is currently unknown. Aims: Investigate in the ON model, potential structural and functional changes of the heart linked to vitamin D deficiency. Methods: Adult rats (n=10) were unilaterally obstructed at the ureteropelvic level. An inductor of vitamin D receptor (VDR) was administered for 15 days IP (30ng/Kg/day). We evaluated histological, molecular and biochemical parameters, as well, cardiac electrophysiological activity with ischemia-reperfusion protocol. Results: we found changes in action potential duration (APD) at 90% (* P
