ORJUELA, Alejandro; VANEGAS, Diego I  e  MONTENEGRO, Juan. Experience in implant of cardiac stimulation devices. Rev. Colomb. Cardiol. [online]. 2006, vol.12, n.6, pp.438-442. ISSN 0120-5633.

We present the data of the implants of pacemakers from the group of electrophysiology that attends patients of two different geographic areas of the Colombian territory, in order to obtain appropriate parameters regarding the more frequent diagnosis, type of stimulation and implant techniques. Methods: 1.004 patients were followed during an average of 41 months. All electro-physiologists used a standardized technique. In the last years, the position of the ventricular electrode varied, using the right ventricle out-going tract and the interventricular septum. The implant’s reports and the clinical histories of almost all patients were reviewed. Results: the most frequent diagnosis was sinus node disease in 43% of patients, followed by complete atrio-ventricular block in 40%. 60% received bicameral stimulation, including patients with sinus node disease for its probability of progression to complete atrio-ventricular block. 33% of the patients received a monocameral stimulation device. Total complications were 3.8%, being the most common the displacement of the ventricular electrode. Conclusions: in the results published by a Colombian group of electrophysiology, similar data to those published in the world literature in regard to indications of pace-makers’ implant, stimulation types and incidence of complications were found. Prospective studies are required in order to evaluate the long- term impact of septal stimulation and stimulation of the right ventricle out-going tract, as well as of the progression to complete AV block in patients with sinus node disease.
