AN AUDIT OF THE COMPLICATIONS OF DUAL AND SINGLE CHAMBER PACEMAKER IN ADULT PATIENTS FOLLOWED OVER A PERIOD OF ONE YEAR

Objective: to determine the frequency of dual and single chamber pacemaker complications in adults.methodology: this study was conducted in 151 pacemaker implanted patients and they were followedevery month for 1 year, for evaluation / programming of pacemaker function and examining for devicerelated complications.results: out of 151 patients with pacemaker, 111(73.5%) patients received single chamber pacemaker and40(26.5%) patients were implanted with dual chamber pacemakers. in one year follow up 21(13.9%)patients developed different complications while 130 patients had uneventful follow up. the differentcomplications seen were infection 9(6%) patients, lead displacement 4(2.6%) patients, heart failure3(2.0%) patients, pacemaker syndrome, lead fracture, diaphragmatic twitching, pocket hematoma andkeloid formation at scar site was noted in 1(0.7%) patient each. as a whole complications in singlechamber was 73.5% compared to patient with dual chamber pacemaker which was 26.5%.conclusion: the rate of complications associated with ppm is not significant, but the rate ofcomplications were more in single chamber pacemaker compared to dual chamber pacemaker. infectionwas the major complication seen
