Usual assessment of left atrial size by 2-dimensional echocardiography in the anteroposterior dimension often underestimates the true atrial size. We compared 15 young patients (< or =50 years old) with lone paroxysmal atrial fibrillation to age-matched controls, and measured atrial size in the inferosuperior and mediolateral dimensions. These additional measurements and atrial volumes were significantly increased compared with control patients, revealing that patients with apparent "lone" paroxysmal atrial fibrillation may have subtle structural abnormalities of the left atrium.
二维超声心动图通常通过前后径对左心房大小进行评估，这往往会低估心房的真实大小。我们将15例年龄小于或等于50岁的孤立性阵发性房颤年轻患者与年龄匹配的对照组进行比较，并测量了心房的上下径和内外径。与对照组患者相比，这些额外测量的心房径线和心房容积显著增加，这表明表面上“孤立性”阵发性房颤患者可能存在左心房细微的结构异常。
