本病发展缓慢,临床上除原有肺、胸疾病的各种症状和体征外,主要是逐步出现肺、心功能不全及其他器官损害的征象。 1.肺、心功能代偿期(包括缓解期)病人活动后感心悸、乏力、呼吸困难和劳动时耐力下降。受凉感冒时,咳嗽、咳痰、气短加重。体检有桶状胸,肺叩诊呈过清音,肝浊音界下降。听诊呼吸音减弱,常闻干、湿性罗音。右室增大常因肺气肿而不易叩出其浊音界。肺动脉瓣区第二心音亢进提示肺动脉高压,三尖瓣区收缩期杂音及剑突下心脏收缩期搏动,多提示右心室肥厚、扩大。
The slow development of the disease, clinically in addition to the original lung, chest disease, a variety of symptoms and signs, the main is the progressive emergence of lung, heart failure and other signs of organ damage. 1. Lung, heart function compensatory period (including remission) patients with heart palpitations, fatigue, difficulty breathing and labor endurance decline. Cold, cold, cough, sputum, shortness of breath worse. Physical examination with a barrel chest, lung percussion showed a voiceless, dull liver sector decline. Auscultation breath sounds weakened, often heard dry, wet rales. Right ventricular enlargement often difficult to knock out the voiding sector due to emphysema. Pulmonary valve area of the second heart sound hyperthyroidism prompted pulmonary hypertension, tricuspid valve systolic murmur and cardiac xiphoid systolic beats, and more tips right ventricular hypertrophy and expansion.
