Ventricular arrhythmia in chronic kidney disease patients.

Patients with chronic kidney disease (CKD) are susceptible to the occurrence of ventricular arrhythmias. The leading cause of death in dialysis patients is cardiac arrhythmias. The pathophysiology of arrhythmias in this population is complex and seems to be related to structural cardiac abnormalities caused by CKD, associated with several triggers, such as water and electrolyte disorders, hormonal conditions, arrhythmogenic drugs, and the dialysis procedure itself. Little is known about the clinical outcomes in CKD patients with asymptomatic ventricular arrhythmias. The results of treatments with anti-arrhythmic drugs and invasive devices are controversial in these patients, according to the available literature. The aim of this study was to review this often-neglected topic, which is of special importance in the CKD population.
