报告的超声心动图发现右心房崩溃的敏感性诊断局部局部崩溃范围为50%至100%;特异性范围从33%到100%。其在鉴定右心室塌陷的敏感度范围为48%至100%,而特异性范围为72%至100%。右心房或右心室的崩溃是不可靠的,除非在坦克德的风险高,与贝叶斯定理一致。如果患者具有低血压,心动过速,呼吸困难,静脉压力增加和心包积液,则可能会持续暗示局部局部的诊断。为了解释Pulsus悖论,大多数超声心动图报告都调用了Dornhorst的理论,即右心室的吸气填充通过成功竞争固定的总包装空间(“心室相互依赖”)积极沉淀左心室。然而,心包空间是not修复了坦帕诗歌,但随着灵感增加,右心比左侧更容易崩溃,鉴于它们的相对厚度。脉冲悖论取决于右心的吸气浪涌,夸大了由填写局部局部诱导的脑室的小卒中体积,肺动脉和全身床之间的血管耦合,其中一个到两个心跳的过境时间。
