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.
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时的右心室肥厚及其严重程度。QRS等积分图中的判别分析在房间隔缺损与正常受试者以及不完全性右束支传导阻滞患者之间的鉴别诊断中，比QRST等积分图和等时线图显示出更好的结果。右心室负荷过重的三个参数（肺循环血流量/体循环血流量、右心室收缩压、右心室射血分数）与QRS等积分图和QRS等电位图显示出显著相关性。因此，体表图是评估右心室肥厚的一种有用方法。
