Permanent cardiac pacing in patients on chronic renal dialysis

We reviewed the need for permanent pacemaker implantation in patients with chronic renal failure who were undergoing dialysis. During a 10-year span, there were seven patients undergoing dialysis in whom a permanent pacemaker was indicated; this was an incidence of 0.68%. During that same period, the general patient population of this hospital had an incidence of permanent pacemaker implantation of about 0.29%. The need for hemodialysis in the same hospital population was 0.51%. Of the seven patients, four had universal pacemakers. Cardiac function was evaluated via radionuclide angiography. Three of the four patients showed improvement with dual-chambered pacing over ventricular pacing. Permanent pacemaker implantation was often needed after initiation of dialysis from 6 to 51 months with a mean of 21 months. During the follow-up period, three patients died from 7 months to 6 years after the institution of permanent pacing; their deaths were secondary to renal disease.
