BEHAVIOR OF CARDIAC PACING IN THE MUNICIPALITY OF SAGUA LA GRANDE FROM 2005 TO 2011

摘要

Introduction: Permanent pacemaker implantation is increasingly necessary to achieve a reduction in morbidity and mortality due to cardiovascular disease. Objective: This paper was devised in order to describe the behavior of pacemaker im-plantation in the municipality of Sagua la Grande. Method: A descriptive, longitudinal, prospective and retrospective study was con-ducted in a group of patients who underwent pacemaker implantation at the Mártires del 9 de abril Hospital in Sagua la Grande, Villa Clara, Cuba, from 2005 to 2011. Results: 151 pacemakers were implanted, of which 134 were primary implantations and 19 were reused. In the sample, 59.6% of patients were male, 94% of patients were older than 65 years, and 53% of the implants were performed on an outpatient basis. The most commonly used route was the cephalic vein, which covered 58.3% of the performed procedures. The most common cause was atrioventricular block, in 51% of cases, and the most common complication was the displacement of the elec-trode, which was diagnosed in 3.3% of patients. Conclusions: The patients were mostly elderly, by far (15:1); more pacemakers were implanted in men than in women (1.5:1); the cephalic vein was the most commonly used route (2:1 compared with the subclavian vein). The main cause for implantation was atrioventricular block. The most common complication was the displacement of the electrode and the procedure could be performed on an outpatient basis without increasing the risk
