[Cardiac arrhythmias during dialysis. An unresolved problem].

The incidence of the arrhythmias in 47 patients subjected to chronic hospital dialysis using different techniques has been assessed. Cardiopathies and non-cardiopathies were assessed separately. In the first group, no significant differences were observed with respect to the presence of heart rhythm disturbances. The second group showed increased ventricular arrhythmias during the intradialysis and postdialysis period. A statistical correlation was carried out between the presence of arrhythmias and various parameters (technique of dialysis, weight difference, ultrafiltrate/hour, age). The only statistically significant correlation in the non-cardiopathies was age.
