Abstract
L
eft atrial dilatation is often considered as one of the important causes for atrial fibrillation. In this study we sought to examine the relationship between right atrial dilatation and left ventricular function in patients with atrial fibrillation, and the association with the documented duration of the dysrrhythmia.
30 consecutive patients with chronic atrial fibrillation of more than 6 months duration were investigated by means of clinical history, electrocardiography and echocardiography.
Right atrial dilatation was found in 20. Patients with a dilated right atrium had a larger left atrium, lower left ventricular shortening fraction.
