心声图可以帮助识别心房动 (AF) 患者左心房压升高的情况. septal E/e 的 E/e 的 E/e 的
科学领域:
- 心脏病学 心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 前庭的研究研究.
背景情况:
- 准确评估左心房 (LA) 压力对于管理心房动 (AF) 患者至关重要.
- 在AF患者中估计LA血压升高的非侵入性回声心脏学方法需要进一步验证.
研究的目的:
- 为了确定回声心脏学指数,准确地检测在被诊断为AF的患者中升高的LA压力.
- 评估单个心声回声学参数的有效性和用于检测高LA压力的联合算法.
主要方法:
- 在两个三级医院招募176名AF患者进行导管切除.
- 直接测量穿刺后的LA压力平均值,高压定义为≥15mmHg.
- 进行跨胸腔心声扫描以获得标准参数,包括隔膜E / e'比和LA菌株.
主要成果:
- 在36%的患者中观察到升高的LA压力 (≥15 mmHg).
- Septal E/e'比率显示出与平均LA压力 (r=0.351) 最强的相关性.
- 使用隔膜E/e'比率,LA储压力和LA体积指数的等级算法在识别升高的LA压力时获得了80%的准确性.
结论:
- 隔膜E/e'比是最有效的单一心声学参数,用于识别AF患者的升高的LA压力.
- 结合隔膜E/e'比率,LA储菌株和LA体积指数的组合算法显著提高了识别准确性.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
