The paper describes the changes in P, QRS and T vector orientations in the H plane in the aberrant beats in cases of partial atrioventricular block and premature atrial and ventricular systoles. The sites of possible atrial ectopic foci are discussed in relation to the anatomy of the atrial chambers and the orientation of the P vectors associated with atrial ectopic beats.
本文描述了部分房室传导阻滞、房性早搏和室性早搏病例中异常搏动时H平面上P、QRS和T向量方向的变化。结合心房腔的解剖结构以及与房性异位搏动相关的P向量方向,讨论了可能的房性异位起搏点的位置。
