Abstract

Background: A key procedure of the rhythm control strategy in atrial fibrillation (AF) is cardioversion to normal sinus rhythm. The aim of the present study was to provide a review of treatment patterns for the cardioversion of patients with AF in a hospital setting in Poland and document the success rate of various cardioversion procedures.

Methods: We herein present the results from Poland of a prospective observational study to characterize patients with recent onset episodes of AF for whom cardioversion is one of the planned therapeutic options — the RHYTHM-AF registry. Consecutive patients in the hospital setting, age > 18 years, with documented AF at the time of enrollment, excluding those with atrial flutter and those treated with vernakalant, were recruited. No treatment was recommended nor discouraged.

Results: Five hundred and one patients were recruited (mean age 64.2 ± 12.1), with 294 (58.7%) patients finally undergoing cardioversion. Primary electrical cardioversion (ECV) was successful in 131 (88.5%) patients. Primary pharmacological cardioversion (PCV) was successful in 110 (75.3%) patients. Amiodarone and propafenone were most commonly used (52.1% and 24.7%, respectively). Fourteen complications and adverse events were recorded (no stroke was observed).

Conclusions: Conversion to sinus rhythm was attempted in < 60% of the patients with AF admitted to the hospital with an intention to terminate arrhythmia. ECV was successful in ~90% of the patients, while PCV in ~75% of the patients (amiodarone and propafenone were most commonly used). The rate of complications was low (2.8%).
