1
Acute suppression is more likely in patients with greater dispersion of right atrial refractoriness between these two sites.
2
The doses of amiodarone converting the arrhythmias increased atrial refractoriness, whereas the effects on AV nodal conduction and refractoriness were variable.
3
The results support the concept that atrial flutter is due to circus movement where the flutter rate is dependent upon atrial refractoriness.
