20 subjects with parietal ventricular block, detected by Frank vectoracardiogram, were submitted to phono-mechanographic examination. Prolongation of PEP was shown; the second period of electromechanical interval (A-C interval in apex-cardiogram) was given in detail. Isovolumetric contraction, systolic ejection time and diastolic period were normal. This pattern is quite typical for parietal block and completely differs from bundle blocks and cardiomyopathies. Therefore it may be useful in differntial diagnosis of these kinds of conduction disturbances as well.
通过Frank心向量图检测出20例患有室壁传导阻滞的受试者接受了心音-机械图检查。结果显示射血前期（PEP）延长；详细给出了机电间期的第二个时期（心尖心动图中的A-C间期）。等容收缩期、射血期和舒张期均正常。这种模式对于室壁传导阻滞来说相当典型，与束支传导阻滞和心肌病完全不同。因此，它在这些类型的传导障碍的鉴别诊断中可能也很有用。
