Answers are grounded in this paper and cite their sources.
The presence of dual muscular CS-LA connections with unidirectional block provides an electrophysiological substrate for reentry and arrhythmia induction in patients with refractory AF.
Rate-dependent eccentric CS-LA conduction block is associated with AF/atrial flutter induction in patients with drug-refractory AF undergoing ablation. The presence of dual muscular CS-LA connections, coupled with unidirectional block in one limb, seems to serve as a substrate for single or multiple reentry beats, and arrhythmia induction.
