Polarcardiograms using the posteroanterior axis as the polar axis were recorded in 112 cases of the clinically healthy subjects. QRS wave with small notch or slur both in front and behind of the main triangular configuration with narrow base were most frequently observed in the frontal magnitude ECG. T wave showed simple monophasic upright wave with the mildly sloping ascending limb and the relatively rapidly sloping descending limb. The magnitude of the maximum QRS vector and the maximum QRS vector time in frontal plane were very similar with those of the spatial QRS vector. The quantitative values obtained by the measurement of the polarcardiograms agreed well with those obtained by the vectorcardiograms reported by the various authors. Polarcardiography made possible not only to know the polar coordinates of the cardiac vector at any instant very easily, but also to express the time-related curve of the polar coordinates, which vary as a function of time, in easily understandable analogue pattern. QRS and T waves of the magnitude, the alpha-longitude and P-A latitude ECG in the normal subjects were classified into the several definite patterns.
以前后轴为极轴记录了112例临床健康受试者的极坐标心电图。在额面心电图中，最常观察到的QRS波在主三角形结构前后有小切迹或顿挫，基底部狭窄。T波呈简单的单相直立波，上升支轻度倾斜，下降支相对快速倾斜。额面最大QRS向量和最大QRS向量时间与空间QRS向量非常相似。通过极坐标心电图测量获得的定量值与不同作者报道的向量心电图获得的值吻合良好。极坐标心电图不仅能非常容易地随时了解心脏向量的极坐标，还能以易于理解的模拟模式表达随时间变化的极坐标的时间相关曲线。正常受试者的额面、α-经度和P-A纬度心电图的QRS波和T波被分为几种确定的模式。
