心源性休克或充血性心力衰竭导致左室泵衰竭仍是急性心肌梗塞住院死亡的主要原因。左室收缩力的减弱取决于梗塞心肌范围的大小以及室壁运动障碍的程度,后者可通过超声心动图检出。本文报道对急性心肌梗塞者采用切面超声心动图法,检查左室壁运动异常的范围和程度,据此估计其左室功能,并和左室功能的临床和血液动力学参数进行比较。方法:44例急性穿壁性心肌梗塞患者,切面超声心动检查采用扇形扫描仪,换能器为2.25兆赫,以每秒30周转速转动,扇形角度30°或82°,每秒成
Cardiac shock or congestive heart failure leading to left ventricular failure is still the main cause of death in hospital with acute myocardial infarction. Decreased left ventricular contractility depends on the size of the infarcted myocardium and the degree of ventricular dyskinesia, which can be detected by echocardiography. This article reports the acute myocardial infarction by sectional echocardiography method to check the scope and extent of left ventricular wall motion abnormalities, thus estimating the left ventricular function, and left ventricular function and clinical and hemodynamic parameters were compared. METHODS: Forty-four patients with acute transmural myocardial infarction were examined by a sector scanner using a sector scanner with a transducer of 2.25 MHz rotating at 30 weeks per second with fan angles of 30 ° or 82 ° per second
