目的:探讨超声心动图在肺栓塞诊断中的价值。方法:66例经临床综合诊断为肺栓塞的患者行超声心动图及外周血管超声检测。结果:66例出现程度不一的右心受累病变的表现,肺动脉干或分支内栓塞4例,右心房内血栓1例,外周血管超声检测下肢静脉栓塞34例,上腔静脉栓塞1例,结论:超声心动图对右心系统的评价和量化分析,对肺栓塞的及时诊断、病情评估、治疗决策具有重要价值。 相似文献

Objective To investigate the effect of cardiac resynchronization therapy (CRT) and the problem of non-response to CRT in patients with chronic heart failure. Methods Twenty patients[(64±10.9) yrs,5 women, 15men] underwent CRT. Conventional echocardiography was performed in each patient before implantation and at 6 months post implantation. Results The clinical response rate was 60% and echocardio-graphic response rate was 55% at 6 month follow-up. Average EF increased 10%. Three patients died and 1 pa-tient was found to have increased left electrode thresholds. One electrode dislocation occurred and recannulation was required. Four patients had no response to CRT. The response rate to CRT was lower in patients with a nar-row QRS or ischemic cardiomyopathy. Conclusion CRT is an effective treatment for chronic heart failure pa-tients. Non-response to CRT may berelated to the cause of heart failure and narrow QRS. 相似文献

心肌致密化不全的超声诊断 总被引:6,自引:0,他引:6
心肌致密化不全是一种罕见的先天性畸形。胚胎早期 ,心脏是由无数肌纤维交织而成的疏松结构 ,由于心内膜形态发生停止而使心肌致密化过程失败。其解剖学特征为无数粗大的肌小梁持续存在 ,小梁间深陷的间隙直达心肌内[1] ,可与其他畸形并存 ,亦可单独存在。资料与方法本研究收集自 1997年以来的 5例患者 ,男 4例 ,女 1例 ,年龄 16~ 48岁 ,平均 3 4岁。均以进行性心功能不全为主要症状 ,均经心电图 (ECG )、超声心动图 (UCG)以及冠状动脉造影检查 ,2例行心内膜心肌活检术。使用美国HP 5 5 0 0型、ATL 5 0 0 0型彩色超声诊断仪 ,融… 相似文献
