Patients with pacemakers
The results of patients with pacemakers compared to data collected from all patients are presented in Table 1. In patients with a history of complete AV block (P < .001) or any AV nodal conduction defect (P < .001), RNRVAS was seen significantly less frequently. In the patients with RNRVAS, presence of VA conduction (P < .001) and sinus node disease (P = .001) were more frequent compared to patients without RNRVAS. ELT induction during atrial threshold test (P < .001), a high atrial pace ratio (P = .030) and a low ventricular pace ratio (P< .001) were significantly more frequent in patients with RNRVAS.
