一、小心脏症候群安静情况下一般无自觉症状,轻度活动时出现眩晕、心悸、呼吸急促、疲劳、胸前疼痛等一系列由于心搏出量不足引起的症状。X线检查心影小于正常,心脏横径一般为9—12cm,心胸比例小于0.41。心电图Ⅰ导联为小的QRs波,Ⅱ、Ⅲ导联为大的QRS波,由于心肌缺氧,二级梯试验出现S—T段下降、T波倒置。临床上多与起立性调节障碍及神经性循环无力症合并存在。二、心肌梗塞后症候群于急性心肌梗塞后2—10周发病。发病可能与心肌梗塞后坏死心肌组织产生的抗原引起自身抗体形成有关。主要临床表现为发热及胸痛。发热一般为38°—39℃,胸痛性质由钝痛至不可忍受的刺痛,自心前区、胸骨区向颈部、肩胛区、上腹部及右季肋部放射,深呼吸时加重,迁延数
First, small heart syndrome Quiet conditions generally no symptoms, mild activity, dizziness, palpitations, shortness of breath, fatigue, chest pain and a series of symptoms due to lack of stroke output. X-ray examination is less than normal heart rate, heart diameter is generally 9-12cm, cardiothoracic ratio of less than 0.41. Lead ECG Ⅰ small QRs wave, Ⅱ, Ⅲ leads for large QRS wave, due to myocardial hypoxia, secondary ladder test S-T segment decreased, T wave inversion. More clinical and standing sexual dysfunction and neural circulatory ailments exist. Second, myocardial infarction syndrome in 2-10 weeks after the onset of acute myocardial infarction. The pathogenesis may be related to the formation of autoantibodies by the antigens produced by necrotic myocardium after myocardial infarction. The main clinical manifestations of fever and chest pain. Fever is generally 38 ° -39 ° C, the nature of the chest pain from dull to unacceptable sting pain, from the anterior heart area, sternal area to the neck, scapular area, upper abdomen and right quarter rib radiation, respiratory distress, exacerbations
