Abstract: Background: Active-fixation screw-in leads are associated with initially high thresholds. However, pacing thresholds have been shown to improve within several minutes after screwin. The aim of this study is to investigate the long-term stability of rapidly improved pacing thresholds following the implantation of active-fixation screw-in leads.Methods: We performed a prospective observational study on 68 consecutive patients, who were referred for an initial pacemaker or implantable cardioverter defibrillator i… Show more

“…These results are almost similar as those noted in the Boston Scientific product performance report (polyurethane insulation leads, 99.4% and 98.7% at 5 and 10 years, respectively; silicon insulation leads, 98.8% and 97.0% at 5 and 10 years, respectively). Some studies have examined changes in the electrical characteristics of the pacing lead in acute and chronic stages [5,6]. However, the long‐term status of the FINELINE II Sterox EZ Lead has not been reported to date.…”

“…In our experience, in the former cases, the thresholds improve after several minutes; therefore, we recommend waiting for approximately 5 m. In these cases, long‐term results are also favorable. Thus, frequent changes in lead position are not always necessary [11].…”
