摘要
目的 测量肺静脉起源的阵发性心房颤动 (房颤 )患者肺静脉的开口直径。方法 连续5 1例肺静脉起源的阵发性房颤患者 ,根据选择性肺静脉造影测定双上肺静脉开口直径和致心律失常的肺静脉开口直径。结果 共发现 76根致心律失常性肺静脉 ,其中左上肺静脉 31根、右上肺静脉 2 9根、左下肺静脉 13根、右下肺静脉 3根。致心律失常的左上和右上肺静脉开口直径分别为 (13 7±0 9)mm和 (13 9± 1 1)mm ,显著粗于非致心律失常的左上和右上肺静脉开口直径 [分别为 (12 8± 1 3)mm和 (13 0± 1 1)mm ,P <0 0 1]。结论 肺静脉起源的阵发性房颤患者致心律失常的肺静脉存在开口部扩张。
Objective The aim of this study is to measure the ostial diameters of pulmonary veins (PVs) in patients with paroxysm al atrial fibrillation (PAF) or iginationg from the PVs Methods The ostial diameters of superior PVs and arrhythmogenic inferior PVs were mea sured by selective PV angiography in 51 consecutive patients with PAF originatin g from the PVs Result A tot a l of 76 arrhythmogenic PVs were founded, included 31 left superior PVs,13 left in ferior PVs,29 right superior PVs,and 3 r ight inferior PVs The ostial diameters o f arrhythmogenic left and right superior PVs[(13 7±0 9)mm and (13 9 ±1 1)mm,respectively] were sig nificantly larger than non arrhythmogeni c left and right superior PVs[(12 8± 1 3)mm vs(13 0±1 1)mm,[WTB X]
