随着心脏听诊技术的普遍提高,心音图、特别是超声心动图的广泛应用,功能性二尖瓣狭窄的检出率大大提高了。由于听诊的局限性,单凭心脏听诊的结果来诊断心脏病是片面的,容易做出错误的结论,常易把功能性二尖瓣狭窄误诊为风湿性心脏病二尖瓣狭窄,现将误诊病例报告分析如下(见附表)。 With the general improvement of cardiac auscultation techniques, the application of phonocardiogram, especially echocardiography, has greatly increased the detection rate of functional mitral stenosis. Due to the limitations of auscultation, the diagnosis of heart disease based on the results of heart auscultation is one-sided and prone to make erroneous conclusions. It is often easy to misdiagnose functional mitral stenosis as rheumatic mitral stenosis and is now misdiagnosed The case report is analyzed as follows (see attached table).
