Methods
Patients with DDD mode CIEDs [177 patients, 67.5 ± 14.8 (70) years; 70
women] were included. Atrial threshold test was done in DDD mode at a
rate at least 10 beats above the basal heart rate, with an AV delay of
300 ms (range 250 - 350). A multivariable logistic regression model was
used to assess the independent predictors of RNRVAS.
