原发性扩张性心肌病是以心室扩张,射血分数降低为特征的一种原因不明的心肌疾病,多见于左心受累或全心扩大。而单纯右心扩大者,国内仅见二例报道,现将我院遇到的以单纯右心扩火,射血分数降低,心律失常为表现的一例报道如下:病历摘要:患者男性,62岁,住院号15550。因阵发性心悸、胸闷10年并晕厥2次入院。无慢性咳喘史。查体:血压110/70mmHg,口唇无紫绀,无颈静脉怒张,胸廓无畸形,心率80次/分,律齐,A_2=P_2,未闻及病理性杂音,双肺清,肝脾不大,下肢不肿。心电图:窦性心律,QRSV_1呈 rs 型,V_5呈 QRS 型,动态心动图:多形室性早搏,平均每小时197次,阵发
Primary dilated cardiomyopathy is an unexplained cardiomyopathy characterized by a decrease in ventricular dilatation and ejection fraction, which is more common in patients with left ventricular involvement or generalized enlargement. The simple right heart enlargement, only two cases reported in our country, now encountered in our hospital with a simple right heart fire, lower ejection fraction, arrhythmia as an example of the performance of the report is as follows: Patient male, 62 years old, Hospital number 15550. Due to paroxysmal palpitations, chest tightness and syncope for 10 years 2 admissions. No chronic cough history.
