[Cardiac arrhythmias during dialysis. An unresolved problem]. / Aritmie cardiache in corso di dialisi. Un problema non risolto.

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.

[Persistent left superior vena cava in patients treated with a definitive pacemaker. Incidence in the population and follow-up of particular pacemakers]. / Vena cava superiore sinistra persistente in pazienti trattati con cardiostimolazione definitiva. Incidenza nella popolazione e follow-up di impianti particolari.

Four cases of persistent left superior vena cava encountered during the placing of a definitive pacemaker are reported. The incidence of the abnormality in the adult population is discussed together with the possible techniques for implanting an electrocatheter in the right ventricle.
