A low anatomical dipole position relative to the carina (≥ 6 cm) predicts loss of proper VDD function in patients with single lead VDD pacing systems.
Hunziker et al. (1998) conducted an observational in high degree AV block with normal sinus node (n=86). Low position of the atrial dipole relative to the carina (≥ 6 cm) was evaluated on loss of proper VDD function (p=<0.02). A low anatomical position of the atrial dipole relative to the carina (≥ 6 cm) independently predicted the loss of proper VDD function in patients with single lead VDD pacing systems (p<0.02).
