二尖瓣狭窄分离术后,血液动力学有了改善,左房及肺动脉压力降低,因而可使心电图发生变化。为明了二尖瓣分离术后心电图变化时期及其与近期症状改善的关系,特分析175例二尖瓣分离术后的心电图变化。资料分析175例二尖瓣狭窄病人中,41例手术证明兼有轻度二尖瓣闭锁不全。年龄最小15岁,最大46岁。男100例,女75例,术前心脏功能,175例中Ⅱ级95例,Ⅲ级57例, Ⅳ级 Mitral stenosis after surgery, hemodynamics have improved, left atrial and pulmonary artery pressure decreased, which can make the ECG changes. In order to clarify the relationship between electrocardiogram changes after mitral valve dissection and its improvement with recent symptoms, ECG changes in 175 patients after mitral valve dissection were analyzed. Data analysis 175 cases of mitral stenosis, 41 cases of surgery proved mild mitral valve insufficiency. The youngest 15 years old, maximum 46 years old. 100 males and 75 females, preoperative heart function, 175 cases of grade Ⅱ 95 cases, Ⅲ grade 57 cases, Ⅳ grade
