WebLeft ventricular leads are often easy to extract. However, when leads have been in place for over 3 months, partial or total occlusion of the main CS and target veins is common.81 Using venoplasty, Zucchelli et al. 82 reported successful LV lead implantation despite subtotal occlusion after lead extraction. Figures 23-70 to 23-73 illustrate the ... WebNov 1, 2024 · Her RA threshold reduced to 0.625 V at 0.4 ms and the RV threshold was 1.0 V at 0.4 ms. Her device output was 3.25 V / 0.40 ms in the RA lead and 2.50 V / 0.40 ms in the RV lead. A corresponding trend was noted in her lead sensing as well.
