Transesophageal echocardiographic evidence of more pronounced left atrial stunning after chemical (propafenone) rather than electrical attempts at cardioversion from atrial fibrillation

Abstract

We studied left atrial function in 55 patients undergoing electrical (n = 23) or chemical (intravenous administration of propafenone, n = 32) attempts at cardioversion from atrial fibrillation. Chemical attempts at cardioversion revealed a significant increase in spontaneous echo contrast and a significant decrease in left atrial appendage Doppler flow, even in patients who did not have successful conversion to sinus rhythm.
