Saudi J Kidney Dis Transpl 2021 Jul-Aug;32(4):1146-1151

Department of Internal Medicine, Nephrology Division, King Fahd Hospital of the University, Al Khobar, Saudi Arabia.

Cardiovascular diseases are the main cause of morbidity and mortality in end-stage renal disease (ESRD) patients. Cardiac arrhythmias are prevalent in patients undergoing hemodialysis (HD), however, dialysis treatment per se can be considered as an arrhythmogenic stimulus. Uremic patients are characterized by a "pro-arrhythmic substrate" because of the high prevalence of ischemic heart disease, left ventricular hypertrophy, and autonomic neuropathy. Read More
