Changes in ventricular repolarization duration associated with HD largely depend on the concentrations of Ca(2+) and K(+) in the dialysis bath. These findings may have important implications for the choice of the electrolytes concentration of the dialysis bath during the HD session.

In patients with uraemia, the haemodialysis session induces a progressive increase in QT interval and modifies its relationship with heart rate. These effects may predispose some individuals to ventricular arrhythmias at the end of and immediately after the haemodialysis session.

Buttonhole: the opposite of what i'Ve always done Abstract. The buttonhole technique (BHT) represents an arteriovenous fistula (AVF) puncture tool that allows positioning the needle always at the same site of either the left or right arm of hemodialysis patients. This procedure is more comfortable for patients, and reduces hemostasis time and aneurysmatic degradation of AVF. Despite BHT been rapidly accepted by patients and nurses, some physicians are still sceptical. BHT requires paying particular attention in managing subcutaneous tunnellization and preserve it for each of the next incannulations. Physicians and nurses need continuous training to minimize infective and/or traumatic complications. BHT should be suggested for each hemodialysis patient with puzzling venipuncture.
