本文报导54例原发性充血型心肌病的超声心动图表现,重点探讨M—型超声心动图对本病的早期诊断与鉴别诊断价值.材料与方法本文就我院78年11月至80年7月底资料较完整,经临床多方面检查确诊的54例(住院31例、门诊23例)充血型心肌病的M—型超声心动图进行分析.54例中男32例女22例,年龄自16~67岁,平均年龄43岁.病程在一年以内的20例,一年以上的34例.检查当时无心衰的(其中绝大多数均有过心衰史)24例,有不同程度充血性心力衰竭的30例.仪器采用武汉无线电研究所研制的XJY—6型M—型超声心动仪,超声频率为2.5兆赫兹. This article reports 54 cases of primary hyperemic cardiomyopathy echocardiography, focusing on the M-echocardiography early diagnosis and differential diagnosis of the disease.Materials and MethodsIn this paper, our hospital 78 years from November to 80 years At the end of July, the data were more complete and were analyzed by M-mode echocardiography of 54 cases (31 inpatients and 23 outpatients) confirmed by clinical examination. There were 32 males and 22 females in 54 cases 16 to 67 years old, mean age 43 years old.Of course, 20 cases within one year, 34 cases more than one year.Examination at that time no heart failure (most of them had a history of heart failure) in 24 cases, to varying degrees 30 cases of congestive heart failure.The instrument uses the Wuhan Institute of Radio XJY-6 type M-type echocardiography, ultrasonic frequency of 2.5 MHz.
