Study limitations
In this study we weren’t able to evaluate the relationship between real
life incidence of RNRVAS occurrence and loss of atrial capture due to
the lack of algorithm capabilities. In this study, atrial threshold test
was specifically designed to demonstrate the relationship between loss
of atrial capture and RNRVAS. The settings used in the atrial threshold
test are different from the real life settings of the participants. Our
results prove that when predisposing conditions are present, RNRVAS is
easily induced. The observed frequency of RNRVAS in our study may be a
lot higher than clinical frequency because the specific predisposing
settings of the atrial threshold test are different from the regularly
used settings of the patients. Further studies are needed to evaluate
the relationship between RNRVAS inducibility with atrial threshold test
and RNRVAS incidence in AHRE recordings.
