RESUMO
OBJECTIVE:
To assess the incidence of problems requiring reprogramming of atrioventricular pacemakers in a long-term follow-up, and also the causes for this procedure.METHODS:
During the period from May '98 to December '99, 657 patients were retrospectively studied, An actuarial curve for the event reprogramming of the stimulation mode was drawn.RESULTS:
The follow-up period ranged from 12 to 178 months (mean = 81 months). Eighty-two (12.4 percent) patients underwent reprogramming of the stimulation mode as follows 63 (9.5 percent) changed to VVI,(R/C); 10 (1.5 percent) changed to DVI,C; 6 (0.9 percent) changed to VDD,C; and 3 (0.5 percent) changed to DOO. The causes for the reprogramming were as follows arrhythmia conducted by the pacemaker in 39 (37.6 percent) patients; loss of atrial sensitivity or capture, or both, in 39 (38.6 percent) patients; and microfracture of atrial electrode in 5 (4.9 percent) patients. The stimulation mode reprogramming free probability after 15 years was 58 percent.CONCLUSION:
In a long-term follow-up, the atrioventricular pacemaker provided a low incidence of complications, a high probability of permanence in the DDD,C mode, and the most common cause of reprogramming was arrhythmia conducted by the pacemaker
