Objective: To determine the efficacy and safety of temporary pacing with an active fixation lead placed trough the internal jugular vein and/or subclavian vein. Methods: We analyzed a consecutive series of 25 out of 73 patients that had a pacemaker extraction and were pacing dependent requiring temporary pacing with an active fixation lead until the new pacemaker implant, from 2017 to 2021. Results: After extraction 25 patients age 68 years ±16 years, required temporary pacing, the media for temporary pacing was 5 days. There were no mortality associated to temporary stimulation. Only one patient (4%) had a complication 4 days after the implant with capture fail due to a microdislogement requiring reintervention. Conclusion: Temporary stimulation through active fixation pacemaker lead it is safe and effective.
