[Results of cardiac pacing: about 188 patients]

ABSTRACT

Indications for permanent pacing are currently well codified. This treatment may, however, present complications. To report the results of cardiac pacing and to identify predictive factors of pacing's complication. We conducted a retrospective study of 188 consecutive patients admitted to the cardiology department of Mongi Slim university hospital in La Marsa between January 2005 and June 2011 and implanted with a single or dual chamber pacemaker. In our study, we had 92 men and 96 women [sexratio= 0.95]. The mean age was 70.21 +/- 13 years. The indication for cardiac pacing was a high degree heart block in 74.46% of cases and a sick sinus syndrome in 15.95% of cases. The degeneration conduction tissue was the main etiology [72.34% of patients]. Success implantation was obtained in 98.4%of cases. The main operative complication was the pneumothorax in 3 patients [1.59% of cases]. At Long term, cumulative survival rate was 78.95%. Only operating time affects significantly the rate of early complications [p<0.001]. Late complications were related to the valvular heart disease [p = 0.007], the ischemic etiology [p = 0.05], the oral antivitamine K treatment [p = 0.04] and the occurrence of early complication [p = 0.002]. Our hospital, which is considered as a small Center of cardiac pacing [less than 80 procedures/year] had a low complication rate as well as big centers
