  • 摘要:Active-fixation pacing leads allow the use of selective pacing sites. We evaluated their long-term performance versus passive-fixation leads in 199 newly implanted patients (n = 100 active and n = 99 passive). Postoperative pacing thresholds in the active group were higher than in the passive group (0.85 ± 0.31 V vs. 0.53 ± 0.21 V at baseline, P P = 0.003). The passive thresholds slightly increased to 0.72 ± 0.31 V at five years. Differences between groups were significant until three years (all P vs. 683.14 ± 110.98Ω at baseline), and both showed significant reductions at one month to 537.96 ± 147.43Ω in the active group, and after three months to 643.85 ± 82.40Ω in the passive group (both P vs. baseline). Impedance differences between groups were significant until four years (all P
