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.
