To prospectively investigate the timing and factors associated with the occurrence of atrial fibrillation（AF）in hemodialysis（HD）, we studied 24 HD patients with cardiac implantable electrical devices（male : n＝16, mean age : 74±10 years, Pacemaker : n＝18, Implantable cardioverter defibrillator : n＝3, Cardiac resynchronization therapy defibrillator : n＝3）. We analyzed the occurrence-timing and burden of AF from device-stored data during a mean follow-up period of 9±1 months. Sixteen patients（67％）had at least one AF event. Furthermore, AF events per hour were significantly more frequent during HD than during the other periods without HD（p＜0.01）. The AF burden per hour was significantly higher during HD and from 24 hours before HD to the start of HD than at the other times（p＜0.05）. Patients with AF during HD had significantly lower serum potassium levels than those without AF（4.4±0.2mEq/L vs 4.7±0.2mEq/L, p＝0.01）. The incidence of AF during HD was higher, and low serum potassium level was associated with AF occurrence in HD patients.
