Abstract:Transthoracic Doppler echocardiography was per-formed in68consecutive patients with right ventricular in-farction treated with bedside examination was performed before and at2to3h after thrombolysis re-spectively,and a subsequent follow-up examination was scheduled10d differences were found in echocardiographic findings after the thrombolytic presence of a severe tricuspid regurgitation and of an ab-normal septal motion in patients with acute myocardial infrac-tion indicates involvement of the right echocardiographic findings are helpful for examining the ef-fect of thromolytic therapy on RV dysfunction.

0 引言
由于右心室心肌梗死的预后较差,其治疗方法不同于左室心梗,,心导管血流动力学检查,,肺毛细血管楔压正常或减低[1] ,.

1 对象和方法

对象 68例下壁心梗患者,平均年龄(±)岁,均有典型胸痛30min以上,ECG检查II,,谷草转氨酶血清(GOT)和磷酸激酶(CPK):冠脉造影正常的同期住院患者35例.
方法①检查方案:;②超声心动图检查:在溶栓前和溶栓后2~:左室和右室舒张末期前后径,三尖瓣返流量和返流速度,房间隔和室间隔运动(室间隔收缩期向前运动为异常,房间隔凸向左房为异常).
统计学处理:所有数据用x ±s表示,然后进行均数t检验.

2 结果
溶栓前63例(94%)的患者右室舒
