The bedside examination was performed before and at 2 to 3 h after thrombolysis respectively, and a subsequent follow up examination was scheduled 10 d later. Significant differences were found in echocardiographic findings after the thrombolytic therapy. The presence of a severe tricuspid regurgitation and of an abnormal septal motion in patients with acute myocardial infraction indicates involvement of the right ventricle. The echocardiographic findings are helpful for examining the effect of thromolytic therapy on RV dysfunction.展开更多
急性右心室心肌梗死（acute right ventricular infarction）的发生率约占心肌梗死总检出率的13％～34％，远较左心室心肌梗死为低，且多数同时合并左心室下壁梗死，孤立的右心室心肌梗死少见。随着冠状动脉造影的广泛应用，其显示多数...急性右心室心肌梗死（acute right ventricular infarction）的发生率约占心肌梗死总检出率的13％～34％，远较左心室心肌梗死为低，且多数同时合并左心室下壁梗死，孤立的右心室心肌梗死少见。随着冠状动脉造影的广泛应用，其显示多数急性右心室心肌梗死由右冠状动脉（right coronary artery，RCA）闭塞所致，展开更多
