An 18-year-old patient had right-sided hypertrophic obstructive cardiomyopathy. His case was quite unique in that the intensity of the systolic murmur was apparently decreased during the inspiratory phase and increased during the expiratory phase (reversed Rivero-Carvallo's sign).
一名18岁患者患有右侧肥厚型梗阻性心肌病。他的病例相当独特,即收缩期杂音的强度在吸气期明显减弱,在呼气期增强(逆Rivero-Carvallo征)。
