心脏超声检查时为了检出卵圆孔未闭,常规应用Valsalva动作和咳嗽来增加右向左的分流,但并未见到有关这些动作影响左房内血液回声性质的报道。作者对咳嗽和作Valsalva动作时左房内房间隔附近的血液回声作了观察,旨在明确经食道超声心动图(TEE)造影检查时左房内不同形式显影现象的原因,进一步统一真性卵圆孔未闭的诊断尺度。研究对象为作常规TEE的成年患者30例,采用5MHz换能器,将增益位置调至
In order to detect patent foramen ovale during heart echocardiography, Valsalva motion and coughing were routinely used to increase right-to-left shunts, but no reports were found that these actions affect the echogenic properties of the left atrium. The author of the cough and Valsalva action for the left atrial septum near the blood echo was observed in order to clarify transesophageal echocardiography (TEE) contrast examination of the left atrium in different forms of development of the reasons for the phenomenon, to further unify the true foramen ovale Unclosed diagnostic scale. The study was performed on 30 adult patients with conventional TEE using a 5 MHz transducer to adjust the gain position to
