Widened dispersion of refractoriness has been considered to lead to an increase in atrial vulnerability. In this study, we obtained simultaneous monophasic action potential recordings by 2 special catheters from 2 different loci in the right atrium in 9 normal subjects (Group 1) and in 7 patients with paroxysmal atrial fibrillation (Group 2). We measured action potential duration at 50% (APD50) and 90% (APD90) repolarization from both loci in the right atrium during steady-state through one of… CONTINUE READING
