In V1, this is seen as a taller initial positive deflection of the P wave, more than 1.5 small squares.

在V1导联中，P波呈较高的初始正偏转，＞1。5个小方格。

In V1, P wave is biphasic, with an initial positive deflection corresponding to activation of the right atrium, and a subsequent negative deflection, resulting from activation of the left atrium.

在V1导联中，P波是双相的，初始正偏斜对应于右心房激活，随后负偏斜由左心房激活引起。

In a normal person, the left to right movement of current during depolarization of the intraventricular septum can produce an initial negative deflection in the QRS complex in the left latter leads.

对于正常人，室间隔去极化过程中，电流由左向右运动，可在左后导联QRS复合波中产生初始负偏移。
