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.
