Endocardial High Frequency Stimulation in the Atrial Wall
An alternative approach to monitor CNA involves High-Frequency
Stimulation (HFS) of the GPs via the endocardium18,13.
While this method holds significant academic value in various
applications, including AF ablation30. it presents
certain challenges specific to CNA. Apart from the inherent issues
associated with point-by-point sequential assessment and frequent AF
induction, HFS primarily assesses specific areas of innervation and
cannot provide an estimate of the global innervation resulting from
extensive vagal cardioinhibition. In other words, HFS examines
individual branches rather than the entire neural network.
Radioscopy Time The average duration of radioscopy in the CNA+ECVS group was slightly
longer than in the CNA group (13.6±11 vs. 13.1±3.2 minutes, p=0.87), but
the difference was not statistically significant. However, there was
greater data dispersion in the ECVS group. This variation was due to
cases in which the vagal effect was rapidly eliminated by anatomical
ablation, while in others, it was necessary to expand CNA until vagal
effect abolishment or maximum reduction was achieved.
