RNRVAS, automatic capture test
Considering the results of our study, we think that automatic threshold
tests in the modern devices may increase the incidence of RNRVAS when
predisposing factors are present. Automatic threshold testing algorithms
measure thresholds at least once a day, and are used in most of the
devices today. AHRE recognition algorithms in devices other than St
Jude’s may be unable to detect RNRVAS 11. Based on our
results in this study we recommend that RNRVAS recognition and
prevention algorithms are made mandatory in devices that measure
thresholds automatically. Also, algorithms aiming to decrease
ventricular pacing ratio may also result in RNRVAS. However, in order to
take specific actions, we need more data.
