100 ECGs with left axis deviation have been analyzed with respect to left anterior fascicular block (LAFB). On the basis of conventional criteria LAFB was diagnosed in 59 cases, but could be rules out in 26. Of the remaining 15 ECGs which at first seemed doubtful, 4 were identified as LAFB on the basis of a new criterion: duration of qR in a VL at least 40 msec longer than in V6.
对100份伴有电轴左偏的心电图进行了关于左前分支阻滞（LAFB）的分析。根据传统标准，59例被诊断为LAFB，但26例可排除。在最初看似可疑的其余15份心电图中，根据一项新的标准，有4例被确定为LAFB：aVL导联qR波的时限比V6导联至少长40毫秒。
