心室除极与复极的新见解

New idea on depolarization and repolarization of the ventricles of the heart

提出心电图的QR段属于室间隔和心尖部的除极过程;RS段是心室壁除极过程的前部;T波中部是室间隔和心尖部复极过程的后部;T波后部是心室壁的复极过程;ST段和T波的前部相当于室间隔和心尖部复极过程的前部和中部与心室壁除极过程的中部和后部的重合。同时论述了室间隔和心室壁的除极和复极的扩散方向。这些新见解对于理解和解释异常的QRS波型和ST T改变的生成及其病理意义都有较大帮助。

It is proposed in the article that the QR segment of ECG is the course of de-polarization of the interventricular septum and the apex of the heart, The RSsegment is the anterior part of the course of depolarization of the ventricularwall. The mid part of T wave is the posterior part of the course of repolarizationof the interventricular septum and the apex of the heart. The posterier part of Twave is the course of repolarization of the ventricular wall. The ST segmentand the anterior part of the T wave correspond to the anterior and mid parts ofthe course of repolarization of the interventricular septum and the apex of theheart, and coincide with the mid and posterior parts of the course of depolariz-ation of the ventricular wall. It also proves the disseminating direction of depol-arization a nd repolarization of the interventricular septum and the ventricular wall.
