所谓“哑型”二尖瓣狭窄是指心尖区无舒张期杂音或仅有轻度柔和的收缩期杂音,可称为“哑型”或无杂音的二尖瓣狭窄。我院曾诊治一例报告如下:患者男性,36岁、心悸、气短反复发作十余年,四天前胸骨后闷痛,心悸加重,门诊以“心肌病”入院治疗。查体除心界向两侧扩大,听诊可闻及双肺下散在少许干呜音,心节律绝对不整,强弱不等,心率96次,各瓣膜区未闻及明显杂音,肺肝界在右锁骨中线第六肋间隙,肝右肋下可触及1.0cm、剑下触及不明显,压痛(+),其余检查及化验未见异常。心电图为窦性心律、房性早搏、右心室肥厚顺钟向转位、不完全性右束支传导阻滞,1974年3月13日片心影似二尖瓣型,左肺动脉段隆突,主动脉结变小,心尖园隆,
The so-called “dull” mitral stenosis refers to the absence of diastolic murmur or mildly systolic murmur in the apical area, which can be referred to as “dumb” or murmur-free mitral stenosis. Our hospital had a diagnosis and treatment of a case as follows: The patient male, 36 years old, heart palpitations, shortness of breath more than ten years, four days ago, supraspinatus, palpitations increased, outpatient “cardiomyopathy” admission treatment. In addition to the physical examination to expand to both sides of the auscultation can be heard scattered under the lungs and a little dry arousal, the rhythm of the heart is not the whole irregular strength range, heart rate 96 times, the valve area is not heard and obvious noise, lung and liver in the right Clavicle midline sixth intercostal space, liver right rib can reach 1.0cm, touch the sword is not obvious, tenderness (+), the rest of the examination and laboratory tests showed no abnormalities.
