心源性栓塞性卒中的诊断常常因很难发现血栓或血栓形成的危险因素而受到限制。一部分卒中患者脑缺血原因不明,他们有窦性节律,经胸超声心动描记(TTE)正常,无颈动脉狭窄。本研究的目的就是确定经食道超声心动描记(TEE)对这部分患者的诊断和治疗价值。 对1994年1月～1995年6月有上述特征的30例连续患者进行前瞻性研究。平均年龄62岁(28岁～83岁),男性15例。对这些患者进行了血液分析,心电图
The diagnosis of cardioembolic stroke is often limited by the difficulty of detecting risk factors for thrombosis or thrombosis. Some of the causes of stroke in patients with cerebral ischemia is unknown, they have sinus rhythm, transthoracic echocardiography (TTE) normal, no carotid artery stenosis. The purpose of this study was to determine the diagnostic and therapeutic value of transesophageal echocardiography (TEE) in this subset of patients. Thirty consecutive patients with the above characteristics from January 1994 to June 1995 were prospectively studied. The average age of 62 years (28 years old to 83 years), 15 males. Blood tests, electrocardiograms, were performed on these patients
