室壁激动时间对下壁心肌梗塞合并左前分支阻滞的诊断价值

The diagnostic value of the ventricular activation time on Inferior myocardlol Infarction with left anterior faiclcular block

对7例单纯广泛下壁心肌梗塞和13例下壁心肌梗塞合并左前分支传导阻滞患者的室壁激动时间(VAT)比较分析.结果发现,单纯广泛下壁心肌梗塞组VAT_(aVR)均小于VAT_(aVL),而下壁心肌梗塞合并左前分支传导阻滞组VAT_(aVR)均大于VAT_(aVL).揭示VAT在判断下壁心肌梗塞是否伴有左前分支传导阻滞时具有一定的临床价值.

The ventricular activation time (VAT) of 7 patients with inferior myocardial infarction (IMI) was compared with that of 13 patients with IMI with left anterior (aecicular block (LAFB) in this study, it was shown that in electrocar-diography from all of the patients with IMI, the VAT in lead aVR was shorter than that in lead aVL, in contrast with IMI the VAT in aVR was longer in IMI with LAFB. It is implied that the comparison of VAT in lead aVR with that in lead aVL is helpful to the diagnosis whether the IMI is with LAFB or not.
