限制性心肌病的血液动力学特征是左右心室充盈压升高伴有正常或接近正常的收缩期功能(喷血分数>50％),舒张期一开始时心室压力明显下降,至舒张早期时迅速上升。心室舒张期压力呈下凹-高平顶波型,在压力曲线上表现为y下降伴随快速上升和高平顶,类似“平方根”曲线,如同时记录右和左心室舒张期压力,两者可重叠或相差在3～4毫米汞柱以内。因此,其血液动力学发现和缩窄性心包
Hemodynamic characteristics of restrictive cardiomyopathy are the right and left ventricular filling pressure rise with normal or near normal systolic function (spurt score> 50%), the beginning of diastolic ventricular pressure decreased significantly to early rapid diastolic rise. Ventricular diastolic pressure was concave - high flat top type, the pressure curve showed a decline in y with rapid rise and high flat top, similar to the “square root” curve, such as simultaneous recording of right and left ventricular diastolic pressure, the two can overlap or A difference of 3 ~ 4 mm Hg. Therefore, its hemodynamic findings and constrictive pericardium
