To investigate two conditions that have been poorly investigated in the medical literature before in the context of atrial fibrillation: the coexistence and association of right or left bundle branch block and axis deviation in patients with permanent atrial fibrillation compared to the control group of healthy subjects with sinus rhythm.
We conducted an analytic, retrospective observational study performed at Ziv Medical Center, Safed, Israel, collecting data from medical history records of all patients that have been diagnosed with permanent atrial fibrillation versus healthy controlled patients with normal sinus rhythm. We analyzed their ECGs in order to assess the presence of any bundle branch block and/or axis deviation.
Subjects with atrial fibrillation have significant correlation with left bundle branch block. Subjects with sinus rhythm have significant correlation to left axis deviation. Young subjects (below the age 73.5 y/o) with atrial fibrillation show significantly higher correlation with left bundle branch block and older subjects (above the age 73.5 y/o) with sinus rhythm show significantly higher correlation to left axis deviation.
There is a correlation between atrial fibrillation and left bundle branch block. The presence of left bundle branch block could be a risk factor for atrial fibrillation and the presence of left axis deviation could be a protective factor. There is no difference between female and male patients. There is a difference in the age group; young subjects with atrial fibrillation have a significant correlation with left bundle branch block, which may demonstrate a poor prognosis for patients with atrial fibrillation.
在心房颤动的背景下，研究医学文献中之前研究较少的两种情况：与窦性心律的健康对照组相比，永久性心房颤动患者右束支或左束支传导阻滞与电轴偏移的共存及关联。
我们在以色列萨费德的齐夫医疗中心进行了一项分析性回顾性观察研究，收集所有被诊断为永久性心房颤动患者与窦性心律正常的健康对照患者的病史记录数据。我们分析他们的心电图，以评估是否存在任何束支传导阻滞和/或电轴偏移。
心房颤动患者与左束支传导阻滞有显著相关性。窦性心律患者与左电轴偏移有显著相关性。年轻的心房颤动患者（年龄低于73.5岁）与左束支传导阻滞的相关性显著更高，而年龄较大的窦性心律患者（年龄高于73.5岁）与左电轴偏移的相关性显著更高。
心房颤动与左束支传导阻滞之间存在相关性。左束支传导阻滞的存在可能是心房颤动的一个危险因素，而左电轴偏移的存在可能是一个保护因素。男女患者之间没有差异。年龄组存在差异；年轻的心房颤动患者与左束支传导阻滞有显著相关性，这可能表明心房颤动患者预后较差。
