The Authors describe a case in which an anterior mediastinal tumor manifested as a cardiovascular disease. Phonocardiographic findings and their modifications induced by respiratory manoeuvres are presented and discussed. Particular enphasis is given to the disappearance, with deep inspiration, of the pulmonary ejection murmur associated with the simultaneous paradoxical behaviour of pulmonary component of the second sound. The Authors suggest that such findings can be indicative of pulmonary outflow obstruction by an external mass.
作者描述了一例前纵隔肿瘤表现为心血管疾病的病例。文中展示并讨论了心音图检查结果及其因呼吸动作而产生的变化。特别强调的是，深吸气时，与第二心音肺动脉成分同时出现的矛盾行为相关的肺动脉喷射性杂音消失。作者认为，这些发现可能提示外部肿物导致的肺流出道梗阻。
