Does selective atrial vagal denervation guided by spectral mapping reduce the frequency and length of ventricular pauses in patients with advanced atrioventricular block?
Selective atrial vagal denervation guided by spectral mapping appears to be a safe and effective conservative approach for reducing ventricular pauses in advanced atrioventricular block.
Ablation of the endocardial vagal innervation sites seems to be safe and efficient in reducing the frequency and the length of the ventricular pauses. It was possible by identifying certain spectral components of the atrial electrogram, resulting in a conservative approach.
Rivarola et al. (Thu,) studied this question.
