The SD of mitral and tricuspid annuli were more lower than control group (P<0.01), and E velocity of mitral flow is higher (P<0.01) .
患者较正常对照组心脏二尖瓣环、三尖瓣环下移距离显著减小（P<0.01），二尖瓣E波最大流速显著增大（P<0.01）；
There was obvious difference between the patients with so-called lone AF and the normal group only in the tissue Doppler parameters of mitral ring(P<0.05).
孤立 性 房颤组只有二尖瓣环组织多普勒运动曲线上的参数与对照组差异有统计学意义（P<0.05）。
