引言 近年来,超声心动图在诊断心脏疾病方面已被证明是一种很有价值的方法。运用这一方法在测定正常心脏与患病心脏的形态功能参数方面也取得了进展。安静状态下的超声心动图检查往往提不出多么重要的问题。然而,要在动力性运动中记录到技术满意的超声心动图则必须对仪器进行改进才行。运动超声心动图很重要,因为通常只有对运动中的
Introduction Echocardiography has proven to be a valuable method in the diagnosis of heart disease in recent years. This method has also been used to determine the morphological parameters of normal and diseased heart. Quiet state of echocardiography often can not ask how important questions. However, to record technically satisfactory echocardiography during motorized exercise, the instrument must be improved. Exercise Echocardiography is important because usually only for exercise
