The ECG of 37 patients with atrioventricular discordance were studied and divided in two main groups: I) Situs solitus and II) situs inversus, either a) without associated defects or b) with associated defects. It was concluded: 1) The first vector of ventricular activation, oriented in the same sense of that of atrial activation is a fundamental diagnostic sign; 2) The preponderance of anatomical right ventricle, leads to the diagnosis of unassociated defects; 3) The recognition of biventricular hypertrophy obliges to the diagnosis of associated defects; 4) The AQRS deviation and the shortening in duration of the local electrical systole help to recognized the hypertrofied ventricle and its overload; 5) The presence of right bundle branch block is not in relation to the degree of overloading; 6) The primary alterations of ventricular repolarization are univocal signs of myocardial damage.
对37例房室不一致患者的心电图进行了研究，并分为两个主要组：I）正位心和II）反位心，每组又分为a）无相关缺陷或b）有相关缺陷。得出以下结论：1）心室激动的第一个向量，其方向与心房激动的方向相同，是一个基本的诊断标志；2）解剖学上右心室占优势，提示无相关缺陷的诊断；3）认识到双心室肥大有助于诊断相关缺陷；4）AQRS偏移和局部电收缩期持续时间缩短有助于识别肥厚的心室及其负荷过重；5）右束支传导阻滞的存在与负荷过重程度无关；6）心室复极的原发性改变是心肌损伤的明确标志。
