Does a new automatic threshold tracking algorithm correctly verify ventricular capture in patients with unipolar pacemaker leads?
A novel automatic threshold tracking algorithm accurately verifies ventricular capture beat-by-beat using unipolar leads, potentially expanding the use of automatic threshold tracking beyond low polarization bipolar leads.
Kennergren et al. (2003) studied Pacemaker implantation (n=35). New automatic threshold tracking algorithm for unipolar leads was evaluated on Verification of capture or loss of capture. A new automatic threshold tracking algorithm correctly verified capture or loss of capture for every single analyzed beat across different pacing outputs in all 35 patients.
