我们研究了 QRS 和 QRST 等积分图以及等时线图，用于诊断房间隔缺损和原发性肺动脉高压的右心室肥厚及其严重程度。 QRS等积分图的判别分析显示房间隔缺损与正常人和不完全性右束支传导阻滞患者的鉴别诊断效果优于QRST等积分图和等时线图。右心室超负荷的三个参数（Qp/Qs、右心室收缩压、右心室射血分数）与QRS等积分图和QRS等势图显着相关。因此体表图是评估右心室肥厚的有用方法。
We studied QRS and QRST isointegral maps, and isochrone map for the diagnosis of right ventricular hypertrophy and its severity in atrial septal defects and primary pulmonary hypertensions. The discriminant analysis in QRS isointegral map showed better results for differential diagnosis between atrial septal defects and both normal subjects and incomplete right bundle branch block patients than these in QRST isointegral map and isochrone map. Three parameters (Qp/Qs, systolic right ventricular pressure, right ventricular ejection fraction) for right ventricular overload showed significant correlation with QRS isointegral map and QRS isopotential map. Thus body surface map was an useful method for the evaluation of right ventricular hypertrophy.
