QRS宽度三尖瓣下移畸形右室扩大

　　美国学者的一项研究表明，在三尖瓣下移畸形患者中右室去极化延迟和延长较为常见，并且QRS宽度为右室扩大和功能障碍的标志物。论文于2012年11月1日在线发表于《欧洲心脏杂志》（Eur Heart J）。 　　此项研究纳入了6周内接受心电图和心脏磁共振（CMI）检查的三尖瓣下移畸形患者。伴有相关性先天心脏缺损、既往性右室心肌成形术和（或）减容术、接受I类抗心律失常药物治疗和Q

　　美国学者的一项研究表明，在三尖瓣下移畸形患者中右室去极化延迟和延长较为常见，并且QRS宽度为右室扩大和功能障碍的标志物。论文于2012年11月1日在线发表于《欧洲心脏杂志》（Eur Heart J）。

　　此项研究纳入了6周内接受心电图和心脏磁共振（CMI）检查的三尖瓣下移畸形患者。伴有相关性先天心脏缺损、既往性右室心肌成形术和（或）减容术、接受I类抗心律失常药物治疗和QRS预期的患者被排除在外。对心电图结果以及基于CMR的右室指标和临床特征进行相关性评估。

　　结果显示，63例患者的平均年龄为22±13岁，其中45例（71%）存在右室传导延迟。QRS宽度与右室解剖学舒张期容积相关，并且与右室射血分数呈负相关。碎裂QRS的存在可预测右室房化容积增大（P<0.0001）。QRS宽度正常与右室解剖学舒张期容积较小、右室射血分数较高、心肺运动试验时氧耗较大和运动时氧脱饱和发生率较低相关。
