A case of interatrial block is reported, involving the upper part of left atrium, demonstrated by oesophageal recordings at different levels. Abnormally retrograde atrial depolarisation in the upper part of the left atrium was observed, but normal descending depolarisation in the lower part of the left atrium suggested that interatrial conduction was blocked on the Bachmann bundle but was normal on the middle interatrial pathway. The surface ECG showed a P wave of normal duration; it was inverted in Lead III and a VF, and flat in Lead II with a normal PR interval. The author suggests a method of classification of interatrial block into three types.
报道了一例心房阻滞病例，累及左心房上部，通过不同水平的食管记录得以证实。观察到左心房上部存在异常逆行心房去极化，但左心房下部正常的下行去极化表明，房间传导在巴赫曼束上受阻，但在房间中间路径上正常。体表心电图显示P波时限正常；Ⅲ导联和VF导联P波倒置，Ⅱ导联P波平坦，PR间期正常。作者提出了一种将心房阻滞分为三种类型的分类方法。
