Comparison of Atrial Leads: Importance of Polarity and Fixation Mechanism
Why the study?
Do polarity and fixation mechanisms affect capture/sensing thresholds and complication rates of atrial leads in patients receiving pacemakers?
Population
211 patients (138 male, 73 female, aged 63 ± 14 years) implanted with DDD (n=210) or AAI (n=1) pacemakers.
Comparison
Atrial leads with different polarities and… vs Comparison among the four lead types.
Design
Cohort
Follow-up
12 months

Implication
Equivalent long-term thresholds and safety with active versus passive fixation; supports flexibility in lead choice while leaving open subgroup effects.

I
Intervention
Atrial leads with different polarities and fixation mechanisms (bipolar active fixation, unipolar active fixation, bipolar passive fixation, unipolar passive fixation).
C
Comparator
Comparison among the four lead types.
O
Outcome
Acute and 12-month capture and sensing thresholds, and complication rates.surrogate
Polarity and fixation mechanisms of atrial leads do not have a major impact on long-term capture/sensing thresholds or complication rates.
