Key result
The Medtronic 6971 polyurethane endocardial electrode demonstrated uncommon insulation failure, occurring in only 2.4% of patients over 7 to 70 months of follow-up.
Why the study?
Does the Medtronic 6971 polyurethane endocardial electrode maintain long-term lead integrity and low rates of insulation failure?
Population
82 patients implanted with the 6971 Unipolar Medtronic electrode in the ventricle since 1978.

Does the Medtronic 6971 polyurethane endocardial electrode maintain long-term lead integrity and low rates of insulation failure?
The Medtronic 6971 polyurethane endocardial electrode demonstrates a low incidence of insulation failure over long-term follow-up.
Pirzada et al. (1986) conducted an observational in Ventricular pacing (n=82). Medtronic 6971 Polyurethane Endocardial Electrode was evaluated on Insulation failure. The Medtronic 6971 polyurethane endocardial electrode demonstrated uncommon insulation failure, occurring in only 2.4% of patients over 7 to 70 months of follow-up.
