RNRVAS was observed in the 69 of 177 patients (39.0%). In patients with VA conduction, incidence of RNRVAS increased to 76.7%. The patients with RNRVAS were younger than those without RNRVAS (P = .038). History of complete AV block, any AV node conduction defect (P< .001) and ventricular pacing ratio (P = .001) were significantly higher and VA conduction (P < .001) significantly less in patients without RNRVAS than in patients with RNRVAS. History of complete AV block (P = .009) and ventricular pacing ratio (P = .029) appeared as independent factors indicating decreased risk of RNRVASĀ  development.
