Abstract

ESRD patients have higher cardiovascular mortality risk than the general population. Increased QT dispersion has been shown to be a risk factor for cardiac arrhythmia in chronic hemodialysis patients with diabetes or arterial disease. It is known that QT dispersion is significantly prolonged in postdialysis than in predialysis. It is associated with a decrease in serum potassium. During hemodialysis, serum potassium is decreased and QT dispersion increases. Therefore ventricular arrhythmia frequently occurs in the latter half of dialysis. We report 2 cases of ventricular arrhythmia caused by potassium removal during dialysis in chronic hemodialysis patients.
