Coronary sinus pacing may optimize RA-His timing; leaves open effects on outcomes or practice without higher-level evidence.
Does the site of atrial pacing affect atrial and atrioventricular nodal conduction and refractory periods?
Atrial pacing from the coronary sinus significantly shortens the low septal right atrium to His conduction time compared to high or low lateral right atrial pacing, without affecting AV nodal refractory periods.
FA et al. (1975) studied this question.
