All patients
We observed RNRVAS in 69 of the 177 patients (39.0%). Except age,
history of a complete AV block, any AV nod conduction defect and VA
conduction (Table 1), the baseline clinical characteristics of patients
with and without RNRVAS were similar. The patients with RNRVAS were
younger than those without it (P = .038). History of complete AV
block (P < .001), any AV nod conduction defect
(P < .001) was significantly more prevalent and VA
conduction (P < .001) significantly less in patients
without RNRVAS than in patients with RNRVAS.
Information on CIED is given in Table 1. When patients with and without
RNRVAS were compared, more patients with ICDs displayed RNRVAS compared
to the patients with pacemakers (P = .003). Our results indicate
that the presence of CRTs did not make a significant difference in the
occurrence of RNRVAS. ELT was more frequently triggered during the
atrial threshold test in patients with RNRVAS (P = .003).
Ventricular pace ratio was significantly lower in patients with RNRVAS
(P = .001). Atrial pace ratio was similar in patients with or
without RNRVAS.
