title: New-onset atrial fibrillation: is there need for emergent hospitalization?
abstract: Patients with new-onset atrial fibrillation are often hospitalized emergently. To determine whether this is necessary, the authors retrospectively reviewed the care of 97 consecutive patients with this illness. No reason for the atrial fibrillation in 43 patients could be identified. Hypertension, coronary artery disease, and valvular heart disease were the most commonly associated conditions; myocardial infarction occurred in one patient. In 82% of patients, atrial fibrillation reverted to normal sinus rhythm during hospitalization. Three patients needed emergent hospitalization irrespective of the presence of atrial fibrillation. In the remainder, admission was based solely on the diagnosis of new-onset atrial fibrillation. Ninety-eight per cent had an uncomplicated hospital course. It is concluded that hospitalization is not necessary for all patients with new-onset atrial fibrillation. Those in whom reversion to normal sinus rhythm occurs rapidly during digoxin therapy can be discharged. Where no major medical illness is evident patients can be admitted to a bed outside the intensive care unit until reversion to normal sinus rhythm or rate control is achieved.
