The author calculated the vector (θR & φA) of the electric charge of the hearts of the P-puhnonale by the standard EKG by means of Maekavxt's orthogonal isosceles triangle coordinates. As a whole these are inclined to right, and their rotations are less than the healthy men: and φA are remarkably long, but their continuous times are not so different with healthy men. These are seemed to be caused as follows: to consider the P-wave as previous two report, the times of the stimulous conduction in pathologic right auricles are prolonged, therefore the double times of stinmlous conduction of both auricles are prolonged. Then the author agrees with Takayasu's proposal that such P-wave should be called as "Eight Auricular Predominance".
