层面 / 表现 心脏压塞 缩窄性心包炎
血流动力学
伴血流动力学虚脱的梗阻性休克 [C2] [G6-02] [M5]:
  • 平均右心房压:升高(15–22 mmHg)[C2] [M5]。
  • 平均肺毛细血管楔压:升高并与右心系统压力均等(16–22 mmHg)[M5]。
  • 体循环血压:严重动脉低血压(收缩压 75–88 mmHg,舒张压 55–65 mmHg)伴细弱脉 [C2] [G6-02]。
  • 心输出量:严重减低(1.8–3.2 L/min)[C2]。
  • 左室舒张末期容积:因外在压迫严重减小(< 60–75 mL)[G6-01] [M5]。
  • 左室射血分数(左心室射血分数):在受压心腔中呈代偿性高动力状态(≥ 60–70%)[C2]。
体静脉淤血与充盈压升高且均等 [C2] [M5]:
  • 右心房平均压:升高(14–20 mmHg)[C2] [M5]。
  • 平均肺毛细血管楔压:升高(15–22 mmHg)[M5]。
  • 心输出量:中度减低(3.2–4.8 L/min)[C2]。
  • LV射血分数(左心室射血分数):早期保留(50–65%)[C2]。
  • 体循环动脉血压:正常或处于临界收缩压(收缩压 100–120 mmHg,舒张压 65–80 mmHg)[C2]。
心律
  • 对肾上腺素能刺激反应性出现的显著窦性心动过速(窦性心动过速,心率通常为 110–135 bpm),以代偿减低的每搏输出量 [C2] [G6-02]。
  • 正常窦性心律或心房颤动 [C2] [G6-06]。Ling等人评估了这一临床谱系:“将1985年至1995年间在梅奥诊所评估的135例CP患者(76%为男性)的当代疾病谱与历史队列进行了比较。” [G6-06]。
ECG
  • QRS波群低电压:肢体导联QRS电压 < 0.5 mV [E1] [G6-02]。
  • 电交替:心脏在心包积液幔内呈摆动摇晃运动引起的逐搏QRS振幅变异 [C2] [G6-02]。
  • 持续性窦性心动过速 [C2]。
  • QRS波群低电压:肢体导联QRS电压 < 0.5 mV [E1] [G6-06]。
  • 胸前导联T波弥漫性平坦或倒置 [C2] [G6-06]。
  • 窦性心律下心房增大(二尖瓣型P波)[E1]。
心音与杂音
  • 遥远低钝的心音(经典Beck三联征:低血压、颈静脉充盈怒张、心音遥远)[G6-02]。
  • 心脏杂音缺如 [C2]。
  • 第三心音(S3)或心包叩击音缺如 [G6-02] [M5]。
  • 心包叩击音:在S2主动脉瓣成分后 90–120 ms 记录到的高频舒张早期心音,处于JVP y降的最低谷 [G6-13]。
  • S1与S2心音强度正常;杂音通常缺如 [C2]。
动脉脉搏
  • 重度奇脉:吸气时收缩压下降 > 10 mmHg(常 > 15–25 mmHg)[B5] [C2] [G6-02]。
  • 小容积细弱脉(细脉)伴心动过速 [B4]。
  • 由于每搏输出量减少导致小幅度动脉脉搏(细脉)[B4]。
  • 奇脉通常缺如(绝大多数病例中 < 10 mmHg)[B5] [G6-06]。
颈静脉搏动
  • 极度颈静脉怒张伴极高静脉压(平均静脉压以 cmH₂O 计 > 15–20 cmH₂O)[B3] [C2]。
  • 特征性静脉波形:深而显著的x降支伴由于整个舒张期心室充盈持续受阻导致y降支缺如或基本平坦(y降支缺如)[B3] [G6-02] [M5]。
  • 明显颈静脉怒张(以 cmH₂O 表示的平均静脉压为 14–22 cmH₂O)[B3] [G6-06]。
  • 深而快的“y”降(Friedreich征,深y降):舒张早期心房排空加速且无初始阻力 [B3] [G6-13] [M5]。
  • Kussmaul征阳性(kussmaul):吸气时JVP未能塌陷或反常升高 [B3] [C2]。
负荷试验
  • 吸气:加剧心室相互依赖介导的收缩压下降(> 10 mmHg)[B5] [M5]。
  • 吸气:诱发Kussmaul征(肉眼可见颈静脉充盈加重)并增强心包叩击音 [B3] [G6-13]。
