A clicking, crackling, or crunching sound over the cardiac apex, sometimes followed or accompanied by left-sided chest pain, is usually thought to be caused by pericarditis. It is frequently ignored that these symptoms can be due to a small left-sided pneumothorax, called noisy pneumothorax. The pneumothorax can be visualized on X-ray taken in full expiration. Noisy pneumothorax can be followed by various electrocardiographic changes, thus simulating myocardial infarction and other serious heart diseases. Therefore, it is important to have this differential diagnosis in mind as a possibility when healthy, young people are admitted to the hospital with heart symptoms. Two cases of noisy pneumothorax simulating pericarditis are described.
心尖部出现咔嗒声、噼啪声或嘎吱声，有时伴有左侧胸痛，通常认为是由心包炎引起的。人们常常忽略这些症状可能是由左侧小气胸所致，即所谓的“有声音的气胸”。在完全呼气时拍摄的X线片上可以看到气胸。有声音的气胸可能会伴有各种心电图变化，从而模拟心肌梗死和其他严重心脏病。因此，当健康的年轻人因心脏症状入院时，将这种鉴别诊断作为一种可能性牢记于心很重要。本文描述了两例模拟心包炎的有声音的气胸病例。
