[A comparison of the efficacy of quinidine and kordaron as agents to stabilize the recovered sinus rhythm in patients with the permanent form of atrial fibrillation].

The efficacy of chinidine and cordarone as agents preventing the recurrence of the disturbed sinus rhythm was studied and compared on a material of 459 patients with permanent atrial fibrillation eliminated by electropulse therapy. The sinus rhythm was preserved significantly better in a group of patients given cordarone as a preventive agent, which is confirmed with the aid of a multidimensional statistical analysis as well as an analysis of "competing hypotheses".
