Targeting an electrotonic effect with ablation: Management of a symptomatic long PR interval
2020, HeartRhythm Case ReportsCitation Excerpt :There exists an “electronic interaction” whereby delayed conduction in the slow pathway leads to a voltage difference and resultant current in the surrounding syncytium that prolongs repolarization of the fast pathway.3 This is the putative mechanism whereby ablation of the slow pathway leads to shortening of the fast pathway effective refractory period independent of autonomic tone,2–4 and improvement in fast pathway conduction velocity has also been described.1,5 In the series from Natale and colleagues,1 patients with AV nodal reentrant tachycardia (AVNRT) and a baseline prolonged PR had an average PR interval shortening after slow pathway radiofrequency (RF) ablation of around 70 ms with a maximal shortening of 140 ms, much less than the 255 ms shortening seen in our case.

2010, International Journal of CardiologyCitation Excerpt :This is likely to be less than 3% if the postero-inferior (in the region of coronary sinus ostium) approach is taken [4]. However, the incidence of transient complete AV block during slow pathway ablation remains significant, approximately in 24% of cases [5–9]. Unless the delivery of the radiofrequency energy is immediately interrupted, the risk of permanent damage to normal AV conduction is significantly high [6–9].
