心房纤颤合并室内差异传导,和心房纤颤时出现的室性早搏的鉴别问题常常遇到。在临床心电图上,室上性早搏合并室内差异传导和室性早搏的鉴别,重要点是看P波是否存在的,可是在心房纤颤时,由于没有P波,两者的鉴别就有一定困难。心房纤颤时出现的室内差异传导没有重要意义,但室性早搏对于治疗和预后有很大的影响,所以两者的鉴别是重要的。
Atrial fibrillation with differential conduction indoors, and the presence of atrial fibrillation, premature ventricular contractions identified problems often encountered. In clinical electrocardiogram, supraventricular premature beats with indoor differential transmission and identification of ventricular premature beats, the important point is to see the existence of P wave, but in the atrial fibrillation, the absence of P wave, the identification of the two have some difficulties. Intraventricular differential conduction in atrial fibrillation is not important, but premature ventricular contractions have a great impact on the treatment and prognosis, so the identification of the two is important.
