Short‐ and Long‐Term Results with an Active‐Fixation, Bipolar, Polyurethane‐Insulated Atrial Pacing Lead
Key result
Medtronic 4058 and 4058M bipolar atrial screw-in leads demonstrated a 93.5% 1-year complication-free survival rate, with a tendency toward high pacing thresholds at 3 months.

Glikson et al. (1996) conducted an observational in Atrial pacing (n=136). Medtronic 4058 and 4058M bipolar atrial screw-in leads was evaluated on 1-year complication-free lead survival. Medtronic 4058 and 4058M bipolar atrial screw-in leads demonstrated a 93.5% 1-year complication-free survival rate, with a tendency toward high pacing thresholds at 3 months.
