Two-dimensional echocardiography (2D echo) and Doppler were performed in a group of patients who had a high probability of having right ventricular (RV) dysplasia (left bundle branch block arrhythmias, no signs of cardiopulmonary diseases) and in a group of age-matched normals. 2D echo showed RV morphofunctional abnormalities (free wall and apical irregularities, wall motion abnormalities) in 25% of patients with suspected RV dysplasia but in none of the normals. Concordance with angiography was good (75% of cases with positive 2D echo study had a positive angiography, while only 33% of the patients with suspected RV dysplasia and negative 2D echo had a positive angiography). In patients with high probability of RV dysplasia (positive 2D echo and angiography) left ventricular filling was similar to that of normal subjects whereas RV filling was markedly rearranged, as demonstrated by the significant decrease in RV early-to-atrial peak flow velocities.
对一组极有可能患有右心室（RV）发育异常（左束支传导阻滞性心律失常，无心肺疾病体征）的患者以及一组年龄匹配的正常人群进行了二维超声心动图（2D 超声）和多普勒检查。2D 超声显示，25%疑似 RV 发育异常的患者存在 RV 形态功能异常（游离壁和心尖不规则、壁运动异常），而正常人群中无一例出现此类情况。与血管造影的一致性良好（2D 超声检查阳性的病例中 75%血管造影呈阳性，而疑似 RV 发育异常且 2D 超声检查阴性的患者中只有 33%血管造影呈阳性）。在 RV 发育异常可能性高的患者（2D 超声和血管造影均为阳性）中，左心室充盈情况与正常受试者相似，而 RV 充盈明显重新分布，RV 早期与心房峰值流速显著降低即证明了这一点。
