Dissimilar right atrial rhythms: a case report.
Dissimilar atrial rhythms are generally defined by the coexistence of atrial fibrillation in one atrium and a more regular rhythm in the other atrium, and are reported with left atrial enlargement and/or digitalis toxicity. We report a unique case of dissimilar atrial rhythms controlling two different parts of the same atrium without interfering with one another. The mechanism of the dissociation of two foci is not clear; however, scarring due to previous surgery remains a possibility.
