Spontaneous reversion to normal sinus rhythm after prolonged atrial fibrillation

Abstract

Two patients are reported in whom there was a spontaneous reversion to normal sinus rhythm after atrial fibrillation had persisted ten and fourteen years respectively. One of these patients was an exception to the general rule in as much as there was a clinical improvement when sinus rhythm appeared again. The mechanism underlying such changes in rhythm is not yet fully understood.
