Clinical application of active fixation electrode for right ventricular outflow tract septum pacing

Objective: To evaluate the feasibility and safety of the clinical application of active fixation electrode in right ventricular outflow tract septum pacing. Methods: One hundred and eighteen patients with indication of pacing were studied. Among whom, 40 had sino-atria node syndrome and 78 atrio-ventricular block. All patients were undertaken an active fixation electrode positioned on right ventricular outflow tract septum for pacing. Results: All 118 cases passed successfully through the procedure, with success rate of 98.3% in localization of the electrode at the right ventricular outflow tract septum accompanied by reaching the standardized pace parameters. The adverse incidences included 1 ease of electrode perforation during the procedure, 2 cases of dislocation afterwords (1.7%). Conclusions: The clinical application of active fixation electrode for fight ventricular outflow tract septum pacing is feasible and safety. (authors)
